Embodiment 1

[0045] Add 6.0g of refined cardanol, 1.70g of 37%(w / w) formaldehyde solution, 0.91g of 33%(w / w) methylamine aqueous solution and 15mL of absolute ethanol to 100mL with heating, reflux, stirring device and nitrogen protection In a three-necked flask, the reaction was stirred at 70°C for 24h; the crude product from which ethanol was removed by rotary evaporation was neutralized with 5g of 30% NaOH solution, dried in a vacuum oven, washed with a proper amount of petroleum ether for several times, and then acidified with hydrochloric acid to obtain 6.12g of light pink oil. The oily substance is N,N-bis(1-cardanol methyl)-N-methylamine.

Embodiment 2

[0047] Add 6.0g refined cardanol, 0.65g trioxane, 0.73g n-butylamine and 10mL dichloromethane into a 100mL three-necked flask equipped with heating, refluxing, stirring device and nitrogen protection, heating and refluxing for reaction for 10h; The crude product from which the dichloromethane was removed was neutralized with 5g of 30% NaOH solution, dried in a vacuum oven, washed several times with an appropriate amount of petroleum ether, and then acidified with hydrochloric acid to obtain 6.70g of light pink oil, the oily substance is N,N-bis (1-Cardanol methyl)-N-butylamine.

Embodiment 3

[0049] Add 6.0g of refined cardanol, 0.53g of paraformaldehyde, 1.7g of 33% (w / w) n-propylamine aqueous solution and 15mL of anhydrous methanol into a 100mL three-necked flask with heating, reflux, stirring device and nitrogen protection, heating Reflux reaction for 40h; the crude product from which methanol was removed by rotary evaporation was neutralized with 5g 30% NaOH solution, dried in a vacuum oven, washed with proper amount of petroleum ether several times, and then acidified with hydrochloric acid to obtain 5.70g pale pink oil, the oily substance is N,N-bis(1-cardanol methyl)-N-propylamine.

Abstract

The invention relates to a cardanol phenolic-group non-ionic type dimeric surfactant, the natural product, namely cardanol is used as the raw material, and the cardanol phenolic-group non-ionic type dimeric surfactant is compounded with high yield after alkylamine coupling and a subsequent ethoxylation reaction. The raw material, namely the cardanol is from cashew nut shells which are natural products, low in cost, easy to obtain and sustainable, and high-added-value development and utilization of a large amount of cashew nut shell waste are facilitated. The synthetic method is high in atom economy. The superior cardanol phenolic-group non-ionic type dimeric surfactant which is deuterogenic from natural cardanol is obtained through the process route which is short in synthetic route, convenient to process and high in product yield and superior. The technological process is corrosion free and pollution free and can not generate any harmful compound, so that the technology has good environment friendliness. The raw material of the surfactant is wide in source and low in cost, the technological route is short, production cost is low and economy is good.

Description

Technical field [0001] The invention relates to a nonionic cardanol-based gemini surfactant and a synthesis method thereof, belonging to the field of organic chemistry. Background technique [0002] Surfactants are widely used in various industries and are known as "industrial monosodium glutamate". With the development of science and technology and the progress of modern civilization, traditional surfactants are increasingly unable to meet the needs of society. The green and functionalization of surfactants has become a new direction for industry development in recent years. Compared with traditional surfactants; Gemini surfactants have higher surface activity, lower critical micelle concentration and more functions. However, the synthesis of most Gemini surfactants is still at the laboratory stage due to the difficulty of synthesis and the high price. Research on the industrialization process of Gemini surfactant synthesis and the development of new varieties and new processe...
