Raw materials formula for synthetic sucrose fatty ester and synthetic method thereof

Abstract

The invention discloses a raw materials formula for synthetic sucrose fatty ester and a synthetic method thereof, belonging to the chemical field. The raw materials formula includes, based on the weight part, 50 to 100 parts of sucrose, 20 to 80 parts of fatty acid methyl ester or ethyl ester, 0.2 to 8 parts of catalyst, 5 to 50 parts of fatty acid cationic soap salt, 1 to 20 parts of modified phospholipids, 0 to 8 parts of sucrose ester (HLB is 5 to 15) and 0 to 6 parts of sodium lactate. In the invention, the method that the composite catalyst is added in the system for synthesizing sucrose ester by the solvent-free method is adopted. The modified phospholipids are added so that the reaction in the system for synthesizing sucrose ester is more uniform, the congruent melting can reach rapidly, thus effectively improving the conversion rate of the sucrose ester and the content of the sucrose monoesters and total esters in the products.

Description

technical field [0001] The invention relates to a raw material formula for synthesizing sucrose fatty acid ester and a synthesis method thereof, belonging to the field of chemical industry. Background technique [0002] Sucrose Fatty Acid Esters (Stucrose Fatty Acid Esters referred to as SE) is a non-ionic surfactant with excellent performance and very safe. Commonwealth and Japan, China, the United States and other countries have approved food additives, can be used as emulsifiers, stabilizers, lubricants, regulators and antibacterial agents in food, as drugs and adjuvants in medicine, in cosmetics and washing It is used as an emulsifier and humectant in pharmaceuticals, and as a fruit preservative, pesticide adjuvant and plant growth promoter in agriculture. Because sucrose esters are non-toxic and have a wide range of applications, their synthesis and application research has attracted much attention. [0003] At present, most of the industrial synthesis methods of sucr...

AI Technical Summary

Problems solved by technology

Synthesis of sucrose esters by solvent-free method is non-toxic, short in time and low in cost, but it is difficult for sucrose and fatty acid methyl ester (or ethyl ester) in the reaction system to achieve eutectic under the action of a single fatty acid soap, causing a synthetic reaction The system is not uniform, and it is difficult to reach a homogeneous level, resulting in low content of sucrose monoester and total sucrose ester in the reaction product, and low conversion rate

However, sucrose ester products with high monoester content are widely used in many fields such as food and medicine, and the market demand is the largest, so the promotion and application of solvent-free synthesis methods are greatly limited.
