| Use | This product is used in organic synthesis. 98% commercial goods sold abroad, boiling point 72-76 ℃, relative density 1.114, flash point 16 ℃. It is mainly used for the synthesis of acrylate and acrylamide compounds, and also used for the preparation of the intermediate of the anti fog agent I organic synthesis intermediate. Polymer compound monomer. |
| production method | by the action of acrylic acid and phosphorus trichloride, the molar ratio of acrylic acid to phosphorus trichloride is 1:0.333, the two were mixed and heated to boiling. The reaction mixture was slowly cooled to 60-70 °c. The reaction was continued for 15min and then left at room temperature for 2H. The reactant is divided into two layers, the upper layer product is separated, and cuprous chloride is added for vacuum distillation to collect the fraction at 30-40 ℃(18.7kPa), and the fraction at 30-32 ℃(18.7kPa) is redistilled once to collect the fraction, acryloyl chloride was obtained. Yield 66%. |
