| titleOfInvention | Method for producing low-solvent alkyldiketene |
| abstract | (57) [Abstract] (Modified) PROBLEM TO BE SOLVED: To react a carboxylic acid chloride with a tertiary amine in an inert solvent which is immiscible with water, for the time being, without water or steam, and then with water or steam. Provided is a method for producing a low-solvent alkyldiketene produced by distilling with a solvent. SOLUTION: The following formula (I) [In the formula, R 1 represents C 10 to C 30 alkyl or C 10 to C 30 alkenyl, R 2 represents hydrogen or C 1 to C 8 alkyl] A low solvent alkyl diketene of formula II Carboxylic acid chloride of formula III [Wherein R 3 , R 4 and R 5 are C 1 to C 12 alkyl or C 3 to Representing C 12 cycloalkyl] with a tertiary amine in an inert solvent which is immiscible with water, the organic phase being at a temperature of 80 to 130 ° C. and 10 to 500 mbar. It is produced by distilling at a pressure of r and subsequently adding water or steam to distill. |
