摘要： The present invention provides a method for producing a light fatty acid alkyl ester with the formula of R1—COO—R2, and the method comprises a step in which a alkyl ether with formula of R1—O—R2 and a raw gas containing carbon monoxide go through a reactor loaded with a catalyst for carrying out a carbonylation reaction; wherein the catalyst contains an acidic EMT zeolite molecular sieve; wherein R1 and R2 are independently selected from C1-C4 alkyl groups. The present invention has provided a new method for producing light fatty acid alkyl ester. In the method of the present invention, the carbonylation is carried out in the presence of the catalyst containing the acidic EMT zeolite molecular sieve, and the reaction activity is high, and the stability has been significantly improved, meeting the requirement of industrial production.

摘要： A polyfluoroalkyl allyl compound represented by the general formula: CF3(CF2)n(CH2CF2)a(CF2CF2)bCH2CH═CH2  [I] (n:0 to 5, a:1 or 2, b:0 to 3). The polyfluoroalkyl allyl compound is produced by reacting a carboxylic acid allyl adduct represented by the general formula: CF3(CF2)n(CH2CF2)a(CF2CF2)bCH2CHICH2OCOR′  [II] (n, a, and b are as defined above, and R′: a C1-C3 alkyl group) with a transition metal. This method for producing provides a polyfluoroalkyl allyl compound used as a synthetic intermediate for a fluorine-containing alkylsilane compound that can remove free iodine derived from the raw material compound, before a hydrosilylation reaction is performed, without using a metal reagent having a high environmental impact, and that has excellent handling properties.
