Problems solved by technology

Among them, nonylphenol polyoxyethylene ethers have good performance and moderate cost, but the products contain benzene rings, which are non-environmental-friendly products; the performance of fatty alcohol polyoxyethylene ethers is slightly worse than that of nonylphenol polyoxyethylene ethers, and some Field application performance does not meet the requirements, the cost is moderate, and is an environmentally friendly product; isomeric alcohol polyoxyethylene ethers have the best performance, are environmentally friendly products, and the cost is high; alcohol ether carboxylate AEC, alcohol ether phosphate monoester PNP is a new type of green and environmentally friendly surfactant with good performance; APG (alkyl glycoside), which belongs to the latest type of green and environmentally friendly surfactant, has excellent performance and has many special properties that other surfactants do not have. The raw materials are natural and renewable resources, but the biggest disadvantage is that the production cost is much higher than ordinary surfactants, so the application is only in some high-end fields, and the market share is at the top of the pyramid.

Embodiment 1

[0062] The corn stalks are loosely packaged with a baler, and the corn stalks are crushed by a grinder and transported to the storage bin. From the storage bin, the corn stalk powder is transported to a 4000kg metering tank through a conveyor belt, and then the corn stalk powder is put into the low-carbon In the alcohol glucosidation reaction kettle (1# kettle), add 16,000kg of ethylene glycol through a metering pump, add 32kg of weighed catalyst p-toluenesulfonic acid, and react for 1.5 hours at a temperature of 160°C; transfer the reacted material to In the centrifuge, separate the liquid phase material; transfer the liquid material to 1# storage tank for storage, then wash with 800kg, 70°C water for 15 minutes, centrifuge and dehydrate for 10 minutes, store the washed water in 2# storage tank, repeat This operation is washed 3 times in total. The solid material after water washing is dried by a drum dryer and packed into storage; the eluted aqueous solution is dehydrated and...

Abstract

The invention provides a surfactant composition comprising the following components in weight percent: 5-12% of fatty acid alkanolamide polyoxyethylene ether glucoside, 5-15% of fatty acid alkanolamide polyoxyethylene ether glucoside carboxylate and 16-37% of any one or mixture of two of dipolymers of the fatty acid alkanolamide polyoxyethylene ether glucoside and the fatty acid alkanolamide polyoxyethylene ether glucoside carboxylate. The invention further provides a method for preparing a surfactant mixture by using corn straws. The surfactant disclosed by the invention is low in cost and simple in process; an alkyl glucoside derivative, namely a novel surfactant, production process and a product are green and environmentally-friendly; raw materials have small dependence on petroleum, the investment of equipment for production is small and a complicated separation procedure does not need to be carried out; and the surface activity performance and the efficiency of the product are greatly improved, the use temperature range of the product is wide, the tolerance of the product to an electrolyte is strong, the greasy dirt removing capability is extremely strong and the hard water resisting effect is good.

Description

technical field [0001] The invention belongs to the technical field of surfactant production, and in particular relates to a surfactant mixture containing alkyl glycoside derivatives prepared from corn stalks and a preparation method thereof. Background technique [0002] Corn stalks are rich in resources, renewable resources, and low in cost, and people are very active in many fields of research on them. In the surfactant industry, people have been looking for new products with sufficient raw materials, safe process, green environmental protection, excellent performance and low cost. Surfactants currently used in large quantities include: alkylbenzene sulfonic acid, AES, alkylphenol polyoxyethylene ether series, fatty alcohol polyoxyethylene ether series, cationic and amphoteric surfactants, and there are many types; commonly used surfactants in the industrial field The main agent is non-ionic surfactant. Among them, nonylphenol polyoxyethylene ethers have good performanc...
