METHOD OF PRODUCING PRIMARY ALKYL ETHERS OF GLYCEROL, SUITABLE AS BIOFUEL ADDITIVE, FROM GLYCEROL Russian patent published in 2013 - IPC C07C41/09 C07C43/10 C07C41/14 

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing primary alkyl ethers of glycerol, which can be used as biofuel or as biofuel additives. The method involves activating treatment of a catalyst, reaction of a primary alcohol with glycerol in molar ratio of primary alcohol to glycerol ranging from 3:1 to 9:1, in the presence of a solid acid catalyst, at temperature ranging from 60 to 300°C for 5-8 hours with average hourly rate of feeding material of about 0.2 h^-1, in a fixed-bed reactor and separating the required glycerol ethers which are converted to said reaction mixture.

EFFECT: disclosed method enables to selectively obtain primary alkyl ethers of glycerol with high output in moderate conditions over a much shorter period of time.
