Abstract

The invention discloses a glucose ester group quaternary ammonium salt cationic surfactant. The structural formula of the glucose ester group quaternary ammonium salt cationic surfactant is shown in the description, wherein Glu is a glucose group, R is a C8-C18 long chain alkyl group, X is chlorine, bromine or iodine, and n equals to 1-3. The glucose ester group quaternary ammonium salt cationic surfactant not only is green, environment-friendly, nontoxic, and free of irritation as sugar-based surfactants but is antiseptic, flexible, antistatic and the like as quaternary ammonium salts, has non-ionic glucose hydrophilicity, has fine compound property and synergistic effect with anionic surfactants, and is multifunctional.

Description

1. Technical field The present invention relates to a kind of surfactant, particularly a kind of cationic surfactant and preparation method thereof, specifically a kind of glucose ester-based quaternary ammonium salt cationic surfactant and its synthetic method. 2. Background technology With the reduction of petroleum resources and the increasing requirements for sustainable development and environmental protection, the use of renewable resources to develop and produce low-toxic or non-toxic and biodegradable, environmentally friendly green surfactants has attracted great attention at home and abroad. China is rich in starch resources, and the use of starch hydrolyzate glucose to develop environmentally friendly and efficient surfactants has high application value. The polyol surfactant derived from glucose not only has excellent performance, but also is non-toxic and non-irritating to the human body, and is easy to biodegrade. In recent years, the application of sugar-bas...
