Problems solved by technology

However, the centralized treatment of car wash wastewater may require substantial capital and extensive retrofitting of existing car washes, and this part of the cost is likely to be passed on to consumers
As a result, some consumers may also turn to unprofessional car wash shops or wash them by themselves, resulting in direct discharge of waste water and seriously affecting the ecological environment.

[0028] The present invention further provides a synthetic method of a liquid gemini type polyether cleaning agent auxiliary agent, comprising the following steps:

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

[0030] (2) Synthesis of unsaturated gemini-type quaternary ammonium salt: put dimethylaminoethanol and maleic anhydride into a reaction kettle, add a small amount of catalyst, react at 110-135°C for 2-6 hours, and remove the generated water in a vacuum to obtain cis Dimethylaminoethanol butenedioate. Ad...

Embodiment 1

[0034]1. Add 10mol of the starter 2-propen-1-ol into the reaction kettle, add 50g of potassium hydroxide catalyst at the same time, start stirring, raise the temperature to about 100°C and vacuumize to about 0.1Mpa, remove the water until the weight ratio of the water is less than 0.1%, then raise the temperature to 160°C, slowly add 200mol of ethylene oxide in batches (about 10mol per batch, weight about 440g), add 200mol of ethylene oxide after the addition, keep it warm for 30min, and then add in batches (about 10mol per batch, weight about 440g) 580g) 150mol propylene oxide, after the completion of the reaction, heat preservation and aging at 160±5°C for 35 minutes, after cooling down to below 80°C, adjust the pH to 6-7 with phosphoric acid to obtain prenol polyether.

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

Embodiment 2

[0039] 1. Add 10mol of the starter 9-octadecen-1-ol into the reaction kettle, add 55g of potassium hydroxide catalyst at the same time, start stirring, raise the temperature to 120°C and vacuumize to about 0.1Mpa, remove the water until the weight ratio of the water is less than 0.1%, slowly add 300mol ethylene oxide in batches (about 10mol per batch, about 440g), add 300mol of ethylene oxide after the addition is completed, and heat it at 140±5°C for 25min, then add 80mol ring Propylene oxide, after the reaction is completed, heat-preserve at 140±5°C for 30 minutes, cool down to 85°C and adjust the pH to 6-7 with phosphoric acid to obtain allyl alcohol polyether.

[0040] 2. Add allyl alcohol polyether and coconut oil prepared in step 1 into the reaction kettle at a molar ratio of 1:0.8 to 1.0, add 0.3mol of p-toluenesulfonic acid as a catalyst, and add 15mol of toluene solvent at the same time , stirring and raising the temperature to 130-140° C. for reflux reaction for 2-4 ...

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...
