1 1 TARIFF PRESERVATION OF SURFACE AREA AND PORE VOLUME IN ORGANO-SEPIOLITE PRODUCTION A METHOD BY WHICH IT IS PROVIDED, THE ADDITIVE MATERIAL OBTAINED BY THIS METHOD, AND A PRODUCTION SYSTEM 5 TECHNICAL FIELD The invention relates to the organophilization of sepiolite with CTAB or a similar quaternary ammonium salt. during this process, organic salts aim to conserve surface area (S_BET) and pore volume (PV). an organo- in which the dose-temperature-time parameters are regulated within a specific process window sepiolite production method and the organoclay additive material obtained by this method and a production 10 It includes the system. PREVIOUS TECHNIQUE Sepiolite, with its fibrous structure, high specific surface area (S_BET) and pore volume (PV) Additives in a wide range of applications such as adsorption, composite and coating formulations. It is considered as a material. The hydrophilic character of raw sepiolite allows it to bond with organic matrices. because it limits compatibility, quaternary ammonium salts (e.g., cetyltrimethylammonium) Surface modification (organophilization) is achieved using bromide (CTAB). In current technology, this modification process typically involves suspending sepiolite in an aqueous medium. This involves adding an organic salt such as CTAB, mixing / contacting for a specific period, then 20 It includes separation (filtration, centrifugation, or sedimentation) and drying steps. However, this In current applications, the desired textural properties of sepiolite are achieved while organophilization is ensured. Protecting it presents a critical technical problem. Studies and... Industrial experience shows that the organic salt dosage, reaction temperature, and processing time are appropriate. If not selected within the specified range, the modification agent may overload the sepiolite surface or 25 The aggregation causes physical blockage of the pores and serious surface accessibility issues. This negative situation indicates a decrease in specific surface area (S_BET) and a significant decrease in BJH pore volume (PV-BJH), particularly corresponding to mesopores. This causes the adsorption capacity of the resulting organo-sepiolite to increase within the composite. 30 such as interface interactions and rheological performance in coating / ink formulations The final application parameters are negatively affected. More importantly, this negative impact... High doses of organic salts, which are frequently used in current techniques to minimize their effects, High temperatures (typically above 70°C) and long processing times (over 6 hours) can damage both the chemical system. This unnecessarily increases both material consumption and energy costs, making the process uneconomical. This reduces its sustainability. This situation is particularly true for industrial-scale production. 35 When considered, this is a significant disadvantage in terms of both cost and environmental impact. 2 2 Therefore, the fundamental technical problem in the current technique lies in the production of organo-sepiolite. While the desired organophilic character is achieved, the initial high S_BET and PV values minimizing process costs by maintaining the highest possible level of preservation. The problem is the inability to strike an optimal balance between them. This invention solves that technical problem. to eliminate it, sepiolite (fractionated) with CTAB or a similar quaternary 5 During the modification phase where ammonium salt is combined, the organic salt dose is 5-30%. (preferably 10-20%), temperature 30-70°C (preferably 50-70°C) and duration 1-6 hours (preferably 3-6 hours) It defines a unique process window within which it is defined. This process window Thanks to this, unnecessary high doses, temperatures, and durations are avoided, while the pores are protected. By minimizing blockage, S_BET retention is at a level of 52% and PV-BJH 10 Its value is maintained at a high level of approximately 0.270 cc / g. The invention also covers raw materials.

The investigations revealed that the current technical state for organophilization of sepiolite is 5 Surface modification, acid activation, usually with quaternary ammonium salts (e.g., CTAB). high-temperature calcination, microwave radiation, or polymeric agents (polyethyleneimine, epoxy) It appears that the existing patent documents encompass various methods, such as chemical inoculation, etc. A large part of it is to increase the surface area of ​​sepiolite or to provide a specific functionality (adsorption, (catalysis, composite reinforcement, flame retardancy, battery separators) to impart acid 10 the process, high-temperature heat treatment (above 400°C) or energy-intensive processes such as microwaves It suggests that, however, in most of these processes, sepiolite needs to be made organophilic. During this process, the loss in BET surface area and BJH pore volume (retention loss) was quantitatively investigated. This is not considered as a textural issue; the process parameters (organic salt dose, temperature, time) are taken into account. The direct impact on the preservation of properties is not systematically studied. 15 While some existing documents claim that a high surface area has been achieved, these claims are... sepiolite is usually structurally altered by aggressive processes such as acid activation or calcification. It relies on modification and pore blockage even when organophilization is not targeted. There is a risk involved. Furthermore, some CTABs used for organophilization purposes in the current technique... In the applications, the effect of the dose-temperature-time relationship on S_BET and PV protection is optimized. No process window has been defined, therefore high chemical doses or harsh conditions cannot be avoided. Textural losses could not be prevented due to reaction conditions, and process costs also increased. This is increasing. The present invention aims to address this technical deficiency by fractionating sepiolite. in which CTAB or a similar quaternary ammonium salt is combined in an aqueous environment During the modification phase, the organic salt dose should be 5-30% (preferably 10-20%), and the temperature should be 30-70°C. a process defined as having a temperature (preferably 50-70°C) and a duration between 1-6 hours (preferably 3-6 hours) By making the window mandatory, organophilization is achieved while S_BET and PV values ​​are maintained. It aims to quantitatively target retention, for example around 52% in S_BET. This allows for the achievement of superior metrics such as ~0.270 cc / g pore volume in BJH with conservation. This approach is known. This method involves energy-intensive acid activation, which is frequently used in current techniques. 30 Low chemical content, without the need for high-temperature calcination or microwave processing. It is possible to produce organo-sepiolite with high textural quality under controlled dosage and moderate temperature conditions. by making it more affordable than existing practices in terms of both cost and environmental sustainability.

In current applications, sepiolite is surface-treated with quaternary ammonium salts (e.g., CTAB). during modification, due to inappropriate chemical dosage, temperature and duration selections. Due to pore closure, there is a significant decrease in BET surface area (S_BET) and BJH pore volume (PV). Losses occur, also due to high chemical doses and / or high temperature / long duration, etc. 15 These conditions negatively affect the process cost. This invention solves this technical problem with sepiolite. (fractionated) and CTAB or a similar quaternary ammonium salt combined in an aqueous medium.

This can be done. When deemed necessary, impurities associated with the raw sepiolite source can be reduced and Acetic acid and / or SHMP are optional additives to improve suspension stability. elements can be added. The invention also includes separation after modification 25 A production method that includes (filtration / sedimentation / centrifugation), optional washing and drying steps.

Thus, the invention is proven with low chemical dose and energy input. Enables the production of organo-sepiolite with high surface area and pore volume conservation.

(preferably 50-70°C) and a specific duration defined as 1-6 hours (preferably 3-6 hours) By applying the process window, unnecessary high doses, high temperatures (above 70°C), and long duration are avoided. The use of processing times (over 6 hours) is avoided, thus saving both chemical input and 10 Energy consumption is significantly reduced, increasing the economic sustainability of the process.
