Abstract

The invention discloses an anacardol surfactant containing trisiloxane and amidogen and a preparation method thereof. The anacardol surfactant containing trisiloxane and amidogen is prepared according to the following method: 1) reacting chloropropyl trisiloxane and diamine to obtain an intermediate I; 2) adding anacardol into a reactor, adding a sulfonating agent, and sulfonating to obtain anacardol sulfoacid; 3) reacting anacardol sulfoacid with epichlorohydrin under an alkaline condition to obtain an intermediate II; and 4) mixing and heating the intermediate I and the intermediate II, performing separation purification on obtained products to obtain the anacardol surfactant containing trisiloxane and amidogen. The anacardol surfactant containing trisiloxane and amidogen provided by the invention has the common performances and characteristics of a silicone type surfactant and an amidogen surfactant, is high in solution surface tension reduction capability, good in emulsifying property, less in irritation to a human body and good in biodegradability, and can be better matched with other types of surfactants so as to be prepared into an emulsifying agent, a wetting agent, a solubilizer and a detergent to be widely used in the industrial field.

Description

technical field [0001] The invention relates to the field of organic chemistry, in particular to a cardanol surfactant containing trisiloxane and amino groups and a preparation method thereof. Background technique [0002] In addition to the properties of ordinary surfactants, trisiloxane-based surfactants have more advantages than ordinary surfactants, can be applied to non-aqueous systems, have lower surface tension, and extremely low physiological toxicity , especially with good wetting and spreading properties. [0003] As a cheap biomass resource, cardanol is derived from the cashew nut shell fluid in tropical cashew tree nuts, which contains a variety of biophenols, mainly including cardol, cardanol, anacardic acid and 2-methylcardol . Cardanol is characterized by low toxicity and easy biodegradability. Therefore take cardanol as the surfactant of raw material production to obtain extensive attention of academia and industry in recent years, existing report is obtai...
