Petrochemicals (also known as petroleum distillates) are chemical products obtained from petroleum by refining. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as corn, palm fruit or sugar cane.

Oleochemical Plasticizers with Thermal and Ultraviolet Radiation Stabilizing Activity for PVC Molding Resins and Process for Obtaining Thereof

The present invention is related with bioplasticizers or primary oleochemical plasticizers and the improved process for obtaining thereof. It refers primarily to epoxydized oleochemical plasticizers produced from vegetable oils, as substitute of traditional petrochemical plasticizers. The process starts with the epoxydized product of natural oils, such as sunflower, linseed, Jatropha curcas, soybean, etc., which are transesterified with an alcohol such as ethylic or methylic, in the presence of a catalyst such as sodium methoxide or sodium hydroxide in order to produce an alkylic esters mixture of the fatty acids that were present in the oil or oil mixture used as raw material in the epoxydized oil production. When the plasticizer obtained by the process already mentioned is used for the formulation of moldable poly(vinyl chloride), PVC, resins; the resulting plastic films get adequate hardness, static and dynamic thermal stability, and plasticizer extractability by solvents, such as n-hexane, gasoline and oil. Besides, when the PVC resin is formulated with a phthalic or terephthalic plasticizers mixture and the bioplasticizer, the bioplasticizer presents a full range solubility and or compatibility with the remainder of the resin compounds. The oxyrane chemical ring of the bioplasticizer is an excellent chemical neutralizer of the HCL that might be formed from the PVC, due to the action or interference of thermal or UV radiation.

The invention relates to the technical field of petrochemical engineering, in particular to a controlled releasing microcapsule for scale prevention, wax prevention or viscosity reduction of an oil well. The invention discloses a solid controlled releasing microcapsule for scale and corrosion prevention in the production process of crude oil and wax prevention or viscosity reduction in the production process of the crude oil as well as a preparation method thereof. Filler comprising an inorganic framework and agent components is arranged in a macromolecule composite membrane. The controlled releasing microcapsule has a stable structure comprising an inside inorganic framework support and an outer-layer macromolecular composite membrane wrapping film, can be used for realizing the slow release of the agent and achieving the aim of maintaining the agent effective for a long term as well as the functions of corrosion inhibition and dispersion. With proper volume and density, the controlled releasing microcapsule can be prevented from being taken away by an extraction solution and can be added through a sleeve; and the controlled releasing microcapsule is simple in process and is strong in maneuverability. According to the controlled releasing microcapsule, volatile matters and harmful components which do harm to the human health are avoided; various components can be basically and slowly dissolved; the labor intensity of workers is reduced; and one-time agent addition can ensure stable operation for 30-90 days.

Environment-friendly epoxy intumescent fire-retardant coating and preparing method thereof

The invention relates to an environment-friendly epoxy intumescent fire-retardant coating and a preparing method thereof, and belongs to the field of functional coatings. The environment-friendly epoxy intumescent fire-retardant coating is prepared from a component A and a component B, wherein the component A uses epoxy resin as a main film forming matter and is added with a reactive diluent, a catalyst, a carbon-forming agent, a foaming agent, fire retardant, auxiliaries and solvent, and the component B is composed of a curing agent, a curing accelerator, pigment filler, auxiliaries, refractory fibers and solvent. In the component A, the ratio of the epoxy resin to the reactive diluent is 1:1-5:1. In the component B, the ratio of the curing agent to the curing accelerator is 1:1-5:1, and the usage quantity of the refractory fibers accounts for 5-50% of the total mass. The environment-friendly epoxy intumescent fire-retardant coating is free of alkylphenol, or halogen compounds, or boron compounds or sulfocompounds. The prepared environment-friendly epoxy intumescent fire-retardant coating is good in acid resistance, alkali resistance, water resistance, ageing resistance and salt mist resistance and is particularly suitable for fire-retardant protection for maritime and severe outdoor environments, the petrochemical industry and places with hydrocarbon fire potential hazards.

Energy-saving and emission-reducing technique for producing propane epoxide by using hydrogen peroxide epoxidation propylene

The invention relates to an energy-saving and emission-reducing technique for producing propane epoxide by using hydrogen peroxide epoxidation propylene, belonging to the field of petrochemical technology. The technique comprises a reaction part, a separation part and a tail gas treatment part, and is characterized in that propylene and hydrogen peroxide have an epoxidation reaction through a Ti-Si molecular sieve at medium pressure and low temperature; the propylene and solvent have higher recovery rate, the propane epoxide meeting the requirement of commercial-grade purity can be obtained by extractive distillation, and the joint product of propylene glycol monomethyl ether can be prepared by azeotropic distillation and purification; after part of tail gas is condensed and absorbed and the propylene is recovered, the tail gas reaches the standard and is discharged; extracting agent, absorbing agent and entrainer which are needed by the technique are in closed cycle in the process flow; and medium-pressure operation is adopted by a propylene tower to ensure water-cooling on the top of the tower, and thermal energy can be recovered by multiple-effect rectification and matching of streams. The technique has the effect and the advantage that the new energy-saving and environment-friendly technique for producing the propane epoxide can generate remarkable economic and social benefits.
