Embodiment 1
[0035] A kind of APEO-free α-phenyl octanol polyoxyethylene ether (10) phosphate emulsifier, the product code name is BO-EO (10) PH, and its preparation process is as follows:
[0036] Step a. In a reaction kettle, use excess benzene as a solvent, add aluminum trichloride catalyst, add octanoyl chloride dropwise at a temperature of 40-70°C, hydrolyze and neutralize after the reaction, and distill under reduced pressure to remove benzene to obtain intermediate Body α-phenyloctanone, for use;
[0037] Step b. In a hydrogenation autoclave, under the conditions of a palladium-carbon catalyst, a temperature of 130-170° C., and a pressure of 2.0-3.0 mPa, α-phenyloctanone is hydrogenated and reduced to obtain α-phenyloctanol, stand-by;
[0038] Step c, put α-phenyloctanol and catalyst KOH into the reaction kettle, then heat up and vacuum dehydrate; after dehydration is completed, after passing through nitrogen replacement, the molar ratio of α-phenyloctanol / ethylene oxide is 1:( 10...
Embodiment 2
[0042]A kind of APEO-free α-phenyloctyl alcohol polyoxyethylene ether (5) ammonium phosphate emulsifier, product code name is BO-EO (5) PNH4, and its preparation process is as follows:
[0043] Step a. In a reaction kettle, use excess benzene as a solvent, add aluminum trichloride catalyst, add octanoyl chloride dropwise at a temperature of 40-70°C, hydrolyze and neutralize after the reaction, and distill under reduced pressure to remove benzene to obtain intermediate Body α-phenyloctanone, for use;
[0044] Step b. In a hydrogenation autoclave, under the conditions of a palladium-carbon catalyst, a temperature of 130-170° C., and a pressure of 2.0-3.0 mPa, α-phenyloctanone is hydrogenated and reduced to obtain α-phenyloctanol, stand-by;
[0045] Step c, put α-phenyloctanol and catalyst KOH into the reaction kettle, then heat up and vacuum dehydrate; after dehydration is completed, after passing through nitrogen replacement, the molar ratio of α-phenyloctanol / ethylene oxide i...
Embodiment 3
[0048] Example 3: After the reaction, hydrolyze, neutralize, and distill under reduced pressure to remove benzene, and obtain the intermediate α-phenylisononyl ketone, which is ready for use;
[0049] Step b. In a hydrogenation autoclave, under the conditions of a palladium-carbon catalyst, a temperature of 130-170° C., and a pressure of 2.0-3.0 mPa, α-phenylisononyl ketone is hydrogenated and reduced to obtain α-phenylisononyl ketone Nonyl alcohol, ready to use;
[0050] Step c, put α-phenylisononyl alcohol and catalyst KOH into the reaction kettle, then heat up and vacuum dehydrate; after dehydration is completed, after nitrogen replacement, the moles of α-phenylisononyl alcohol / ethylene oxide Ratio 1: (4~5) Slowly feed ethylene oxide, control the reaction temperature at 120~140°C, and the pressure is less than 0.2mPa;
[0051] Step d, detection When the reaction reaches the required degree of polymerization (EO) ≈ 4, stop feeding ethylene oxide, the reaction enters the ter...
