  • Patent number: 9090556
    Abstract: The disclosure relates to a process for forming an acyloxy carboxylic acid or a derivative of the acid. A hydroxy acid compound is reacted with a carboxylic acid in a reaction vessel and in the presence of a catalyst, such as in a reactive distillation column containing the catalyst. The reaction product formed in the reaction vessel includes an acyloxy carboxylic acid compound, which can be removed continuously from the vessel in a product stream. Another product stream containing unreacted (excess) carboxylic acid and/or reaction byproducts such as water can be separately removed continuously from the reaction vessel.

  • Patent number: 7321052
    Abstract: A process for the preparation of a fuel oil (diesel fuel or heating oil) composition which is a mixture of an alkanol tranesterified fatty acid ester triglyceride and an acetal of glycerol is described. The process preferably provides a prestep of the formation of at least some of the alkanol transesterified triglyceride containing the glycerol for use in the formation of the acetal of glycerol. The composition can also be formed from a reaction of 1,1-dimethoxy- or 1,1-diethoxyethane and glycerol to form the acetal in the alkanol transesterified triglyceride.
