Embodiment 1

[0047] Embodiment 1 kitchen waste grease prepares epoxy fatty acid methyl ester

[0048] Collect kitchen waste (animal waste from the vegetable market, including chicken, duck, fish viscera, skin, hair);

[0049] Take the kitchen waste oil and remove impurities, and then undergo molecular distillation to obtain the treated oil. The acid value of the treated oil is 1.3;

[0050] The obtained treated oil was mixed with sodium hydroxide and methanol according to the mass ratio of 100:0.25:15, then stirred, and left to stand for 35 minutes after the first reaction at 64°C for 20 minutes to obtain fatty acid methyl esters;

[0051]Take the obtained fatty acid methyl ester, stir, heat up to 45°C, and mix with hydrogen peroxide (the molar ratio of hydrogen peroxide to the number of double bonds in the fatty acid methyl ester is 2.5:1), EDTA (stabilizer and fatty acid methyl ester The mass ratio is 100:0.5) after the second reaction at 55°C for 2.5h, the product is obtained. Through...

Embodiment 2

[0052] Example 2 Preparation of Epoxy Fatty Acid Methyl Ester from Kitchen Waste Grease

[0053] Collect kitchen waste (garbage from various slaughterhouses, including discarded internal organs, skins and fur);

[0054] Take the kitchen waste oil and remove impurities, and then undergo molecular distillation to obtain the treated oil. The acid value of the treated oil is 1.5;

[0055] The obtained treated oil was mixed with sodium hydroxide and methanol according to the mass ratio of 100:0.75:10, then stirred, and left to stand for 25 minutes after the first reaction at 60°C for 30 minutes to obtain fatty acid methyl esters;

[0056] Take the obtained fatty acid methyl ester, stir, heat up to 55°C, and mix with hydrogen peroxide (the molar ratio of hydrogen peroxide to the number of double bonds in fatty acid methyl ester is 4.5:1), urea (stabilizer and fatty acid methyl ester The mass ratio is 100:0.1) at 50°C for 3 hours for the second reaction to obtain the product. Throu...

Embodiment 3

[0057] Example 3 Preparation of Epoxy Fatty Acid Methyl Ester from Kitchen Waste Grease

[0058] Collect kitchen waste (leftovers from various food processing factories and spoiled and spoiled meat products);

[0059] Take the kitchen waste oil and remove impurities, and then undergo molecular distillation to obtain the treated oil. The acid value of the treated oil is 1.4;

[0060] The obtained treated oil was mixed with sodium hydroxide and methanol according to a mass ratio of 100:0.5:12, stirred, and left to stand for 30 minutes after the first reaction at 62°C for 25 minutes to obtain fatty acid methyl esters;

[0061] Take the obtained fatty acid methyl ester, stir, heat up to 50°C, and mix with hydrogen peroxide (the molar ratio of hydrogen peroxide to the number of double bonds in the fatty acid methyl ester is 3:1), 8-hydroxyquinoline (stabilizer The mass ratio of fatty acid methyl ester is 100:0.2) after the second reaction at 52°C for 2.9h, the product is obtained....

Abstract

The invention relates to the bioprocessing field and in particular relates to a method for preparing biological plasticizers-epoxidized fatty acid methyl esters from kitchen waste grease. The method has the beneficial effects that the kitchen waste grease is used as the raw material, is wide in source and low in cost, is renewable, not only meets the requirements of industrial production but also reduces harms to the environment and human health, meets the environmental requirement and is a good substitute of petroleum products; any acid catalyst and stabilizing agent are unnecessary to be added in the epoxidation process, so that the possibility of promoting epoxide ring opening by the acid catalyst is avoided, thus increasing the epoxy value and ensuring simplicity in production and low cost; the project products are biodegradable and do not pollute the environment; the products can be widely applied to plastic and rubber products and the like; after the plasticizer is added, the flexibility, glossiness, cold resistance and heat and light stability of the products can be improved and the dosage of the stabilizing agent can be reduced; epoxidized fatty acid methyl esters have obviously better using effects than epoxidized soybean oil and have the same plasticizing effects as DOP (dioctyl phthalate) and DBP (dibutyl phthalate).

Description

technical field [0001] The invention relates to the field of bioprocessing, in particular to a method for preparing bioplasticizer epoxy fatty acid methyl ester from kitchen waste oil. Background technique [0002] In the urban process, garbage, as a product of metabolism, used to be a burden on urban development, and many cities in the world are surrounded by garbage. Nowadays, garbage is considered to be the most potential and inexhaustible "urban mineral deposit" as "misplaced resources". This is the in-depth understanding of garbage, and it is also an inevitable requirement for urban development. [0003] Domestic waste refers to various wastes discharged by residents in urban waste, and refers to solid waste generated in daily life or activities that provide services for daily life and solid waste that is regarded as domestic waste according to laws and administrative regulations. Divided into four categories: recyclable waste, kitchen waste, hazardous waste and other ...
