Embodiment 1

[0016] 170.0 g of isooctyl alcohol and 4.0 g of Mg-Al composite catalyst were added into a 2.5 L pressure reactor, and the ethylene oxide metering tank and the propylene oxide metering tank were respectively connected to the pressure reactor. Replace the air with nitrogen for 3 times, wait until the temperature of the kettle rises to 135-140° C., keep the system pressure at 0.2-0.3 MPa, start feeding 115.1 g of ethylene oxide, and continue the reaction for 0.5 hours after passing through for 2.0 hours. Begin to feed 75.8g propylene oxide then, pass through in 2.0 hours, continue reaction 1.5 hours. After the reaction is complete, cool, release the pressure, and filter. Move the obtained product into a 1000mL four-neck flask, add 53.1g of phosphorus pentoxide in batches, react at a temperature of 65-70°C for 4.5 hours, then add 2.1g of deionized water, and hydrolyze at a temperature of 80-85°C for 1.0 hour , cooled to obtain a colorless to pale yellow viscous liquid.

Abstract

The invention discloses a method for preparing isooctanol polyoxyethylene polyoxypropylene ether phosphate ester. The method comprises the following step of: adding ethylene oxide into isooctanol serving as an initiator to perform polymerization reaction in the presence of a Mg-Al compound catalyst; adding propylene oxide to perform the polymerization reaction to obtain isooctanol polyoxyethylene polyoxypropylene ether and performing esterification reaction with phosphorus pentoxide; and hydrolyzing by using deionized water to obtain the isooctanol polyoxyethylene polyoxypropylene ether phosphate ester which is a mixture mainly comprising phosphate monoester and phosphate diester. The product prepared by the method of the invention has the characteristics of concentrated alkali resistance, low foam and capacity of quickly promoting water to wet and penetrate fibers and fabrics.

Description

technical field [0001] The invention relates to a preparation method of isooctyl alcohol polyoxyethylene polyoxypropylene ether phosphate, which belongs to the technical field of synthesis of anionic surfactants in organic chemistry. Background technique [0002] Alkali-resistant penetrating agent has important applications in the field of textile industry, especially in pretreatment. Most of the pre-treatment working fluids are carried out in a strong alkali bath, which requires that the penetrant used can still maintain good wettability and permeability in a strong alkali bath. Although the sulfate-type anion penetrant has good penetrating power in concentrated alkali solutions above 250g / L, this type of penetrant has good permeability and alkali resistance stability only when it is high in alkali, and it is easy to produce A large amount of foam brings great inconvenience to the production operation. The invention adopts Mg-Al composite catalyst to synthesize a class of...
