Example Embodiment

[0032] like figure 1 As shown, the preparation method of the triphenylphenol block polyether of the present invention includes the following steps:

[0033] Step S101. The catalyst A and triphenylphenol are put into the glass sealing reactor, and the nitrogen gas (preferably replacing nitrogen is 2 times), evacuated, and the ethylene oxide reaction is introduced after the temperature rise dehydration, resulting in the reaction liquid A; where the temperature of the temperature is 110 ° C, the dehydration time is 1 h, and the epoxy ethane is slowly introduced at 110 ° C to 120 ° C. The reaction pressure is not significantly decreased, and the reaction liquid A is obtained. Moreover, the amount of catalyst A is preferably 3 ‰ of Trisstyrene phenol and total quality of ethylene oxide.

[0034] Step S102. The reaction liquid A is treated by adsorption method, in particular: adding an adsorbent, diatomaceous earth, phosphoric acid and deionized water in the reaction liquid A, and then ...

Abstract

TThe invention relates to tristyrylphenol block polyether, sulfate ammonium salt and a preparation method thereof. The tristyrylphenol block polyether is prepared from tristyrylphenol, ethylene oxide, propylene oxide, a catalyst a and a catalyst b, and the structural formula of the tristyrylphenol block polyether is as follows: m is 10-30, and n is 25-35. According to the present invention, the prepared sulfate ammonium salt has characteristics of narrow molecular weight distribution, low raw material residue and wide application range, and the prepared sulfate ammonium salt has characteristics of low dynamic viscosity, high active matter content, light product color and close-to-neutral pH value, can well meet the requirements of high-end users and use under harsh conditions, and further has effects of permeation, wetting, dispersion and the like.

Description

technical field [0001] The invention belongs to the technical field of surfactants, and in particular relates to a tristyrylphenol block polyether, ammonium sulfate and a preparation method thereof. Background technique [0002] Sulfate-type anionic surfactants have good foaming power, wetting power, emulsifying power and detergency, and can be stable in hard water, and have good washing effect at low temperature. They are widely used in detergents and textile aids. Sulfate surfactants are an essential ingredient in hard surface cleaners such as dishwashing liquids and carpet and upholstery cleaners. The hydrophilic group of the sulfate ester surfactant is connected to the hydrophobic group through the C-O-S bond, and the additional oxygen makes the water solubility better, but it is easily hydrolyzed in acidic medium, which limits its application. [0003] However, the applicant has found that: existing tristyrylphenol block polyethers on the market (the block polyethers a...
