摘要:
A process of producing a perfluorocarboxylic acid fluoride having the formula (1): ##STR1## wherein n is an integer of at least 2, comprising effecting oligomerization of hexafluoropropylene oxide in the presence of an alkali metal fluoride a sulfone or a mixture of a sulfone with an ether having the formula (2):CH.sub.3 O(CH.sub.2 CH.sub.2 O).sub.m CH.sub.3 (2)where m is an integer of 2 to 6. This process makes it possible to improve production yield of hexafluoropropylene oxide oligomers remarkably, and to raise a reaction temperature for the oligomerization, as compared with conventional methods, thereby shortening reaction time therefor.
摘要:
A waste oil, an alkaline oil cake, and a crude fatty acid which are discarded as waste materials or obtained as a by-product in the manufacture of rice salad oil are subjected to hydrolysis in the presence of an alkali so as to efficiently manufacture ferulic acid. The waste materials or by-product accompanying the manufacture of rice salad oil or rice fatty acid, which were disposed of by means of burning in the past, are effectively utilized in the method of the present invention.
