| titleOfInvention | The preparation method of poly carboxylic acid series water reducer polymeric monomer methyl allyl alcohol polyoxyethylene ether |
| abstract | The preparation method of poly carboxylic acid series water reducer polymeric monomer methyl allyl alcohol polyoxyethylene ether, it comprises following processing step: 1) be starting raw material with methallyl alcohol, under an acidic catalyst Eorontrifluoride etherate exists, add oxyethane carry out condensation reaction, obtain methallyl alcohol oligopolymer; 2) add basic catalyst in above-mentioned material, dehydration or separating methanol after 1 hour under the condition of 100 DEG C, then add oxyethane and carry out condensation reaction, then add acetic acid neutralization, obtain methyl allyl alcohol polyoxyethylene ether.Present invention process is simple, safety, and the product relative molecular weight obtained is high and have high iodine number. |
