preparation example Construction

[0191] The preparation of the diesel composition provided by the invention is simple, and only needs to mix the components of the diesel composition uniformly. The various additive components can be directly mixed with the base diesel oil, or the various additive components can be mixed evenly first to obtain the additives, and then the obtained additives can be mixed with the base diesel oil. For the convenience of operation, when the various additive components are mixed uniformly, it can be carried out in the presence of a solvent, and the solvent here can be a polar solvent such as N, N-dimethylformamide (DMF), 1,4-dioxane One or more of ring, tetrahydrofuran (THF), dimethyl sulfoxide (DMSO), pyrrolidone and methylpyrrolidone. It can also be hydrocarbons, especially aromatics such as benzene, toluene, xylene, aromatics diluent oil and their mixtures, and biodiesel.

[0192] In the present invention, described base diesel oil can be pure biodiesel, and described biodiesel ...

Embodiment 1

[0210] In the three-necked flask, add 200 grams (about 0.14mol) of polyisobutylene succinic anhydride (polyisobutylene number average molecular weight is 1200, saponification value is 80 mg KOH / gram, degree of substitution is 1.0) and 200 grams of polyisobutylene succinic anhydride with a distillation range of 159- 185°C 9 Heavy aromatics (platinum reforming bottom material), heated to 80°C and stirred evenly, slowly added 20.2 grams (0.138mol) of triethylenetetramine, heated to 150°C for dehydration reaction for 6 hours under the protection of nitrogen, and separated about 2.4 grams of water to obtain polyisobutylene succinimide, the nitrogen content of which was measured by SH / T 0224 method was 1.9% by weight. Add 25 grams of the above C 9The heavy aromatics are made into about 50% by weight of the diluent, which is used as component a for subsequent use (the amount of component a in the following table 1 refers to the amount of the diluent).

Embodiment 2

[0212] In the three-necked flask, add 18.2 grams (0.096mol) of tetraethylenepentamine, 20 grams of toluene and 200 grams of C with a distillation range of 159-185°C 9 Heavy aromatics (platinum reforming tank bottoms), heated and stirred to 50 ° C, in the presence of nitrogen, slowly added 200 grams (0.107 mol) of polyisobutylene succinic anhydride (polyisobutene base number average molecular weight Mn=900, saponification value 60 mg KOH / g, the degree of substitution is 0.65), heated to 110°C for 3 hours, heated to evaporate toluene, and reacted for 2 hours at 145°C to obtain polyisobutylene succinimide, and its nitrogen content was measured by SH / T 0224 method 2.0% by weight. Then add 20 grams of C 9 The heavy aromatics are made into about 50% by weight dilution, which is used as component a for subsequent use.

Abstract

The invention provides a diesel composition. The diesel composition contains base diesel and an additive, wherein the base diesel contains biodiesel; the additive contains a component a and a component b; the component a contains alkenyl succinimide and / or alkenyl succinic acid amide; and the component b is an arylamine antioxidant and / or a hindered phenol antioxidant. The additive also optionally contains a component c which is a metal passivator. The invention also provides a method for improving oxidation stability of biodiesel. With the pure biodiesel as the base diesel, the diesel composition provided by the invention has better oxidation stability, and with the blend fuel containing biodiesel as the base diesel, the diesel composition has better stability and detergency and dispersibility.

Description

technical field [0001] The invention relates to a diesel composition and a method for improving the oxidation stability of biodiesel. Background technique [0002] With the acceleration of dieselization of vehicles worldwide, the demand for diesel will increase. The depletion of petroleum resources and the improvement of people's awareness of environmental protection have greatly promoted the development of diesel alternative fuels in countries around the world. Biodiesel It has been valued by various countries for its superior environmental protection performance and renewability. [0003] Biodiesel (BD100), also known as fatty acid methyl ester (Fatty Acid Methyl Ester), is based on oil crops such as soybeans and rapeseeds, oily forest fruits such as oil palms and pistachios, engineering microalgae and other oily aquatic plants, and animal fats, Waste cooking oil and other raw materials are obtained through transesterification with alcohols (methanol, ethanol). It is a cl...
