Problems solved by technology

[0006] Furthermore, as known in the industry, in the process of washing and centrifuging, some BPO materials with fine particles will enter the wastewater treatment system with the wastewater after permeation, thus increasing the burden of wastewater treatment on the one hand, and on the other hand, because BPO is a kind of Strong oxidant, extremely unstable in nature, a little carelessness will cause fire and explosion, so it is difficult to store and dispose of the solid waste after being treated by the wastewater treatment system. waste of resources
In addition, in the process of BPO preparation, it is unavoidable that there will be leakage or the BPO product cannot be used normally after being polluted by mechanical impurities. If it is introduced into the wastewater treatment system, the above-mentioned unfavorable factors will also occur
Up to now, although the industry has hoped for a solution, it has neither seen nor heard of an effective strategy. The technical solution to be introduced below is produced under this background

Embodiment 1

[0017] according to figure 1 The process flow shown is for the treatment of contaminated BPO.

[0018] Put any one or more kinds of contaminated BPO in the process of preparing BPO, such as washing, centrifugation, pipeline leakage (emission, leakage, etc.) and scattered on the floor and polluted by mechanical impurities, into the equipped mixer In the reaction kettle with the heater, the contaminated BPO is dissolved by the dimethyl phthalate added in the reaction kettle in advance, and the contaminated BPO dissolution is carried out with the agitator turned on, and at the heating temperature of the heater After stirring for 40 minutes at 40°C, that is, at a dissolution temperature of 40°C, open the bottom valve of the reaction kettle, and filter with suction to obtain a plasticizer solution in which BPO is dissolved, which is used to prepare pasty BPO. However, in the plasticizer solution in which BPO is dissolved, the mass % specific concentration of BPO is 10%.

Embodiment 2

[0020] Only change the dissolution temperature to 10°C, the stirring time to 20min, the solvent to a combination of diisobutyl phthalate and butyl benzyl phthalate, BPO in the plasticizer solution dissolved with BPO The mass % ratio concentration is changed into 0.5%, and all the other are the same as the description to embodiment 1.

Embodiment 3

[0022] Only change the dissolution temperature to 30°, the stirring time to 30min, the solvent to a combination of triethyl phosphate, tributyl phosphate and maleic acid ester, the mass % ratio of BPO in the plasticizer solution dissolved with BPO Concentration is changed into 6%, and all the other are the same as the description to embodiment 1.

Abstract

A treatment method of contaminated BPO (benzoyl peroxide) belongs to the technical field of preparation of organic peroxides and comprises: collecting contaminated BPO from the production step of BPO, charging into a container, dissolving the contaminated BPO through a plasticizer pre-added in the container, removing impurities by suction filtering to obtain a plasticizer solution with dissolved BPO, and using the plasticizer solution with the dissolved BPO to prepare pasty BPO. The treatment method has the advantages that as the method provided herein is simple and has no need for strict equipment and process elements, the method can meet the requirement for actual treatment; as the contaminated BPO from the production process of BPO is collected, is dissolved with the plasticizer and is suction-filtered to obtain the plasticizer solution with dissolved BPO which is used to prepare pasty BPO, it is possible to reduce solid waste production level, relieve the burden of a subsequent wastewater treatment system, avoid environmental damage and ensure safety, and it is also possible to avoid resource waste.

Description

technical field [0001] The invention belongs to the technical field of organic peroxide preparation, and in particular relates to a treatment method for polluted BPO. Background technique [0002] The aforementioned BPO is the abbreviation of the English name (the English name is: Dibenzoyl peroxide), the Chinese name is: benzoyl peroxide (also known as "dibenzoyl peroxide"), and its molecular formula is: C 14 h 10 o 4 , the molecular weight is: 242.22; the structural formula is: [0003] [0004] BPO is a widely used intermediate of fine chemical products. It is used in the polymerization reaction of ethylene, styrene, propylene, vinyl acetate, methacrylate, etc. and various multi-component resins. It can also be used in It is used as a curing agent in the processing of polyester products, and as a crosslinking agent in the processing of silicone rubber and fluororubber. In addition, it can be used as a bleaching agent and decolorizing agent for oil refining and fibe...
