Model quinoline-sensitive ionic liquid and its catalytic preparation of long-chain fatty acid a method of esterification of

The invention discloses a preparation method of a thermo-sensitive ionic liquid and a method for catalyzing a methyl esterification reaction of a long-chain fatty acid by adopting the thermo-sensitive ionic liquid. The structure of the thermo-sensitive ionic liquid is as shown in a general formula (I) and comprises a quinoline cation and anions such as a fluoboric acid radical, a methane sulfonic acid radical and hydrogen sulphate. The preparation method of the thermo-sensitive ionic liquid is mainly characterized in that number of phase states of a system is regulated and controlled by increasing and lowering temperature, namely the system can be in one phase at high temperature and in different phases at room temperature or low temperature after the ionic liquid is rapidly separated from products, so that the whole reaction system guarantees high catalytic efficiency in a homogeneous reaction, separation and recycling are simpler, the disadvantages of limited two-phase catalytic efficiency and difficult recycling of the ionic liquid during homogeneous catalysis are overcome, and a new thought is provided for solving the problems. The general formula (I) is as shown in the specification.
