Problems solved by technology

The research content is mainly focused on turning waste oil into biological materials, but catalytic cracking is required in the conversion process, the cost is too high, and the production process will cause certain environmental pollution, which is not conducive to large-scale comprehensive utilization of waste oil
[0003] Using gutter oil as the basic raw material to prepare soft laundry detergent involves mild chemical reaction conditions and a wide range of raw material sources. Transforming waste gutter oil into detergents with high added value can fundamentally eliminate the impact of gutter oil on humans and the environment. hazards, but there are no relevant reports in the literature

Embodiment 1

[0017] A kind of preparation method of the supple laundry detergent based on waste oil, comprises the following steps:

[0018] Step 1: Weigh 50 parts by mass of gutter oil and add it to the first three-necked flask, add 20 parts by mass of distilled water, then use phosphoric acid to adjust the pH value to 1.0, and heat to 90°C for 1 hour while stirring; Separate the layers, add the upper oil phase to the second three-necked flask, then add 50 parts by mass of distilled water, use concentrated sulfuric acid to adjust the pH value to 2.0, heat to 95°C under stirring conditions, and keep the temperature for 5 hours; the reaction is over Finally, leave to stand for stratification, and the upper oil phase is the intermediate product waste oleic acid, which is sealed and preserved for subsequent use;

[0019] The second step: in the third there-necked bottle, add 30 mass parts of waste oleic acid, 42 mass parts of polyethylene glycol 400, 3 mass parts of p-toluenesulfonic acid and...

Abstract

Provided is a preparation method of a smooth-type liquid laundry detergent on the basis of gutter oil. The method comprises the steps that the gutter oil is hydrolyzed to obtain gutter oleic acid, an esterification reaction is conducted on the gutter oleic acid and polyethylene glycol 400, quaternization is conducted, and polyethylene glycol (400) mono gutter oil acid ester based triethyl ammonium chloride is obtained; polyethylene glycol (400) mono gutter oil acid ester based triethyl ammonium chloride, deionized water, triethanolamine, fatty alcohol-polyoxyethylene ether (AEO-9), sodium citrate, fatty alcohol polyoxyethylene ether sodium sulphate (AES), ethyl alcohol, pigment and essence are put into a container to be slowly stirred, and the smooth-type liquid laundry detergent is prepared after all the substances are completely dissolved and stirred to be uniform. Comprehensive utilization of the gutter oil is achieved, and damage of the gutter oil to human beings and the ecological environment is reduced. Sources of the raw materials adopted in the preparation method are wide, the synthesis technology is simple, solvents used in the reaction process can be recycled, low emission is achieved, the reaction conditions are mild, and the preparation method accords with the greenization requirement of chemical product production.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of waste oil, in particular to a preparation method of a soft laundry liquid based on waste oil. Background technique [0002] Gutter oil mainly comes from waste cooking oil and waste oil from animal slaughterhouses. Gutter oil contains a lot of toxic substances. Once it flows back to the dining table, it will cause irreversible and serious harm to human health. Even if waste oil is discharged, due to its slow degradation rate, there is a certain degree of toxicity to the environment. At present, the comprehensive utilization of waste oil has become one of the research hotspots in the field of chemical materials, and there are a large number of documents, patents and corresponding products at home and abroad. The research content is mainly focused on turning waste oil into biological materials, but catalytic cracking is required in the conversion process, the cost is too high, a...
