Abstract
The invention provides a cardanol novel surfactant containing siloxane. The cardanol novel surfactant has a structural formula as shown in the specification, wherein R presents C15H31. The invention further provides a preparation method of the cardanol novel surfactant containing siloxane. The preparation method comprises the following steps of: enabling chloropropyl trisiloxane and biomass cardanol sulfonated body to react; and separating and purifying to obtain the cardanol novel surfactant containing siloxane. The cardanol novel surfactant containing siloxane disclosed by the invention simultaneously has the performance characteristics of silicon-containing surfactant and cardanol surfactant, is good in dissolution, small in skin irritation, and excellent in biodegradation; moreover, the cardanol novel surfactant has good compatibility with other surfactants, and has surface tension of 18mN / m-24mN / m.
Description
technical field [0001] The invention relates to the field of chemistry, in particular to an organic compound and a preparation method thereof, in particular to a novel siloxane-containing cardanol surfactant and a preparation method thereof. Background technique [0002] Trisiloxane surfactants can reduce the interfacial tension at the oil-water interface, and at the same time can wet and spread on low-energy hydrophobic surfaces, this ability is called "super-wetting" or "super-spreading". Silicon-containing surfactants have very low physiological toxicity and can be used in coatings, textiles, daily chemicals, papermaking, oil fields, agricultural chemicals, etc. Cardanol is an abundant and inexpensive renewable biomass resource with low toxicity and biodegradability. Therefore, surfactants produced with cardanol as raw materials have received extensive attention from academia and industry in recent years, but the surface activity of cardanol surfactants is not as good as...
