Therefore, the surfactants produced with cardanol as raw materials have received extensive attention from academia and industry in recent years. For example, CN200910017036.X reported a method for preparing cardanol polyoxyethylene ethers, but so far the cardanol surface activity Surfactants are not as active as silicone-based surfactants

Abstract
The invention provides a cardanol ether surfactant containing trisiloxane. The cardanol ether surfactant has the structural formula as shown in the specification, wherein R represents C15H31; and n is an integer of 2-20. The invention further provides a preparation method of the cardanol ether surfactant containing trisiloxane. The preparation method comprises the following steps of: enabling hloropropyl trisiloxane and cardanol polyoxyethylene ether to react; and separating and purifying to obtain the cardanol ether surfactant containing trisiloxane. The cardanol ether surfactant containing trisiloxane 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 ether surfactant has good compatibility with other surfactants, so that the cardanol ether surfactant containing trisiloxane with different ethylene oxide addition numbers can be obtained; besides, the cardanol ether surfactant can be prepared into an emulsifying agent, a wetting agent, a solubilizing agent, a cleaning agent and the like.
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 cardanol ether type surfactant containing trisiloxane and a preparation method thereof. Background technique [0002] Trisiloxane surfactants can reduce the interfacial tension of the oil-water interface and at the same time wet and expand on low-energy hydrophobic surfaces. This ability is called "super wettability" or "super spreadability". The physiological toxicity of silicon-containing surfactants is very low, and can be used in coatings, textiles, daily chemicals, papermaking, oil fields, agricultural chemicals, etc. Cardanol is an abundant and cheap renewable biomass resource with low toxicity and biodegradability. Therefore, the surfactants produced with cardanol as raw materials have received extensive attention from academia and industry in recent years. For example, CN200910017036.X reported a method for...
