Problems solved by technology

[0003] The traditional esterification temperature is 200-280°C. The main defects of the traditional process are that the color is too heavy, the acid value of the product exceeds 3mgkoh / g, the reaction of the material is not complete, and the saponification value of the traditional process is less than 90mgkoh / g. It is very difficult, the biggest disadvantage is layered
[0004] The traditional process requires decolorization, and some use hydrogen peroxide, activated clay, activated carbon, and diatomaceous earth. The disadvantages of using hydrogen peroxide are residues and high energy consumption caused by dehydration. The biggest disadvantage of decolorization with activated clay, activated carbon, and diatomaceous earth is Adsorption products cause loss and secondary environmental pollution due to filtration, so neither the national standard nor the traditional process is far from meeting the conditions of use in the food industry, cosmetics industry, and pharmaceutical industry

Abstract

A PEG-40 polyglycerol-10 oleate, prepared from the following raw materials in parts by weight: polyglycerol-10,240-540 parts, oleic acid 140-180 parts, PEG-40 (polyethylene glycol) 400-630 parts, antioxidant 0.001-0.002 part, catalyst 0.05-0.1 part, co-catalyst 0.05-0.1 part. Compared with the prior art, the beneficial effects of the present invention are: the introduction of PEG-40 enables the product to be lower in reaction temperature, lighter in color, and the HLB value can be increased to 14 under the condition that the original property basis is not reduced. Above, the transparency is better, the product is odorless, free of impurities, more reasonable in structure, excellent in performance, easy to biodegrade, and free of three wastes.

Description

technical field [0001] The invention relates to the technical field of nonionic surfactants, in particular to a PEG-40 polyglycerol-10 oleate and a preparation method. Background technique [0002] Polyglycerol oleate belongs to the category of polyglycerol fatty acid ester, the national standard Gb1886.178-2016. The color is light yellow to brown, the acid value is ≤12mgkoh / g, the saponification value is in line with the claim, the traditional technology needs decolorization in the production process , Decolorizing agents include hydrogen peroxide, activated carbon, activated clay, diatomaceous earth, etc. [0003] The traditional esterification temperature is 200-280℃. The main defects of the traditional process are that the color is too heavy, the acid value of the product exceeds 3mgkoh / g, the material reaction is not complete, and the saponification value of the traditional process is very difficult to be lower than 90mgkoh / g. The biggest disadvantage is layering. [...
