Example Embodiment

[0028] The present invention further provides a method for synthesizing a liquid gemini type polyether cleaning agent auxiliary agent, which includes the following steps:

[0029] (1) Synthesis of enol polyether: add the starter unsaturated fatty alcohol into the reaction kettle, at the same time add the catalyst potassium hydroxide, start stirring, heat up to 80-120℃, and remove by vacuum or molecular sieve adsorption dehydration The weight ratio of water to water is less than 0.3%, and then the temperature is raised to 150~170℃, ethylene oxide is added, after the addition, the temperature is maintained at 135~165℃ for 25~40min, and then propylene oxide is added. Heat preservation and aging at 165°C for 30 to 45 minutes to obtain unsaturated enol polyether.

[0030] (2) Synthesis of unsaturated gemini quaternary ammonium salt: Put dimethylaminoethanol and maleic anhydride into the reactor, add a small amount of catalyst, react at 110-135°C for 2-6 hours, remove the generated water...

[0033] Example 1

[0034] 1. Add 10mol of the initiator 2-propene-1-ol into the reaction kettle, and at the same time add 50g of potassium hydroxide catalyst, start stirring, heat up to about 100°C and vacuum to about 0.1Mpa, remove the water until the water weight ratio is less than 0.1%, then heat up to 160℃, slowly add 200mol of ethylene oxide in batches (add about 10mol for each batch, weigh about 440g), after the addition, heat and mature for 30min, then add in batches (add about 10mol for each batch, weigh about 440g) 580g) 150mol of propylene oxide, after the reaction is completed, 160±5℃ heat preservation and maturation for 35min, after cooling to lower than 80℃, adjust to pH=6~7 with phosphoric acid to obtain prenol polyether.

[0035] 2. Put 20mol of dimethylaminoethanol and 10mol of maleic anhydride into the reaction kettle, add 0.01mol of catalyst, raise the temperature to 125°C, and remove the water produced by the reaction. After 4 hours of reaction, the temperature ...

[0038] Example 2

[0039] 1. Add 10 mol of 9-octadecen-1-ol as the starting agent to the reaction kettle, and at the same time add 55g of potassium hydroxide catalyst, start stirring, heat up to 120°C and evacuate to about 0.1Mpa, remove the water until the water weight ratio is less than 0.1%, slowly add 300mol of ethylene oxide in batches (approximately 10mol, approximately 440g per batch), after the addition, heat and mature at 140±5℃ for 25min, and then add 80mol ring in batches (add approximately 10mol per batch, approximately 580g) Propylene oxide, after the completion of the reaction, the temperature is maintained at 140±5°C for 30min, and after the temperature is lowered to 85°C, the pH is adjusted to 6-7 with phosphoric acid to obtain allyl alcohol polyether.

[0040] 2. Add the allyl alcohol polyether prepared in step 1 to the coconut oil acid molar ratio of 1:0.8 to 1.0 into the reaction kettle, add 0.3 mol of p-toluenesulfonic acid as a catalyst, and add 15 mol of tolue...

Abstract

The invention discloses a novel cleaning agent additive. The cleaning agent additive is a liquid gemini polyether cleaning agent additive, the main ingredient of the cleaning agent additive is gemini polyether, and the general structural formula of the gemini polyether is shown in the description, wherein a, b, c and d are integers from 0 to 8 respectively, e is an integer from 8 to 30, f is an integer from 8 to 20, g is an integer from 1 to 18, m, n and p are integers from 2 to 10 respectively, R is a higher fatty acid group or hydrogen, X is Cl or Br, Y is hydrogen or sodium or potassium, EO is ethylene oxide, and PO is propylene oxide. The invention further discloses a synthetic method of the novel cleaning agent additive.

Description

technical field [0001] The invention relates to a novel cleaning agent auxiliary agent and a synthesis method thereof, in particular to a novel gemini type polyether cleaning agent auxiliary agent and a synthesis method thereof. Background technique [0002] With the popularization of cars, the market prospect of car cleaning is promising. There are many car cleaning agents on the market, but the overall composition is similar, generally containing additives such as water glass, trisodium phosphate and alkylphenol polyoxyethylene ether. Water glass and trisodium phosphate are strong alkaline substances, and trisodium phosphate contains phosphorus, which can easily cause soil pH imbalance and eutrophication. Alkylphenol polyoxyethylene ether is an environmental hormone, which may produce estrogen-like effects when absorbed by the human body, seriously endangering the normal physiological process of the human body. Today, with the increasing awareness of environmental protec...
