Problems solved by technology

However, due to the unpleasant smell of silkworm chrysalis after high temperature treatment, it is difficult for people to accept it as food, which leads to the limitation of its application field and consumption
At present, although there are many studies on the deodorization of silkworm chrysalis, there is no report on successfully removing the peculiar smell.

Embodiment 1

[0023] See attached figure 1 , which is a process flow diagram for the preparation of N-fatty acyl amino acid sodium surfactant in the present embodiment.

[0024] Step 1: Rinse the reeled silk pupae or machine-made silk floss pupae repeatedly with water, place them in an oven at 80°C for 2-5 hours, and dry them for 2-5 hours. When the water content is lower than 5%, pulverize the silkworm pupae. Weigh 1 kg of silkworm chrysalis powder into an extraction container, then add 4 L of n-hexane, and extract at 40 °C for 3 hours. At this time, the color of the extraction mixed solution is orange, and then the n-hexane is recovered by a rotary evaporator, and about 230 g of fat is obtained at the same time, also known as pupa oil, which accounts for about 23% of the dried silkworm pupae, and most of the remaining components are defatted silkworm pupae Protein powder is about 650 g, accounting for about 65% of the total weight of dry silkworm chrysalis.

[0025] Step 2: Weigh 200 g ...

Abstract

The invention relates to a N-fatty acyl amino acid sodium surfactant and a preparation method thereof, belonging to the technical field of applied chemistry. It uses silkworm chrysalis as a synthetic raw material. Firstly, the dried silkworm chrysalis is crushed, and the vegetable oil is used to extract the solvent to degrease. After recovering the solvent, the pupa oil and defatted pupa powder are obtained; the silkworm chrysalis fatty acid obtained after the pupa oil is hydrolyzed reacts with thionyl chloride to form fatty acid chloride The defatted chrysalis powder is hydrolyzed with high-temperature and high-pressure acid to produce silkworm chrysalis amino acid mixture, and the purified silkworm chrysalis mixes amino acids and fatty acyl chlorides to make N-fatty acyl amino acid sodium using the Schotton-Bowman synthesis method. The biodegradable amino acid anionic surfactant synthesized by the invention has excellent surface activity performance and strong decontamination ability, and can be widely used in shower gel, shampoo, facial cleanser, beard cream and the like.

Description

technical field [0001] The invention relates to a technology for preparing N-fatty acyl amino acid type surfactant completely using silkworm chrysalis, a by-product of silk processing, as a synthetic raw material. The invention also relates to the technical fields of regeneration and utilization of silkworm chrysalis resources and applied chemistry. Background technique [0002] Surfactants are an important class of chemical products with a wide range of applications and a large demand. With the development of science and technology and the enhancement of environmental awareness, people's pursuit of the quality of various products is gradually improving. Therefore, environmentally friendly and functional surfactant products have gradually been valued and favored. [0003] N-fatty acyl amino acid surfactant is a class of fatty acid and amino acid as raw materials prepared by chemical method, because of its superior biocompatibility and easy degradability, it has been obtaine...
