Abstract
A process for producing .omega.-alkene-1-ols which comprises reacting an .alpha.,.omega.-alkanediol having 4 to 14 carbon atoms with a fatty acid selected from the group consisting of stearic acid, palmitic acid and a mixture of stearic acid and palmitic acid.
Claims4
A process for producing an .omega.-alkene-1-ol which comprises heating an .alpha.,.omega.-alkanediol having 4 to 14 carbon atoms together with a fatty acid selected from the group consisting of stearic acid, palmitic acid and a mixture thereof, the molar ratio of said fatty acid to said .alpha.,.omega.-alkanediol being about 1:0.8 to 1:3.0, at a temperature of about 310.degree. to 360.degree. C. in the absence of a catalyst, and continuously feeding the .alpha.,.omega.-alkanediol to the reaction system, with the pressure of the reaction system being controlled to 200 to 700 mmHg, while maintaining the same temperature and simultaneously distilling the .omega.-alkene-1-ol.
