| titleOfInvention | The manufacture method of (methyl) acrylate |
| abstract | The present invention provides the manufacture method of a kind of (methyl) acrylate。The manufacture method of described (methyl) acrylate is characterised by more than 90 DEG C and carries out the distillation of operation (3) under 130 DEG C of temperature below, comprise: (1) makes the fatty acid anhydride shown in following formula (I) react with (methyl) acrylic acid, while the fatty acid limit removing by-product manufactures the operation of (methyl) acrylic anhydride, in formula (I), R 1 Represent the alkyl or alkenyl of the carbon number 1～3 of straight or branched, R 2 Represent the alkyl of the carbon number 1～3 of straight or branched；(2) make unpurified (methyl) acrylic anhydride that phenol obtains with the reaction by described operation (1) react and obtain the operation of (methyl) acrylate；(3) (methyl) acrylic acid operation is reclaimed by distilling。 |
