Choe Jong Gil, associate professor and PhD at the organic chemistry institute, is also a proficient researcher.
He recently developed a method of making and recycling a catalyst for synthesizing ethylene-based vinyl acetate, an important component part for establishing C1 chemical industry.
Vinyl acetate is one of the raw materials of organic chemical industry which is used in the largest amount in the world at present.
According to experts, it is the key issue to set up a process of producing vinyl acetate from ethylene which starts from anthracite coal, especially to obtain a catalyst for synthesizing vinyl acetate which is used in this process.
The vinyl acetate synthesizing technology with ethylene as a raw material has been set as a patent.
Choe conducted intensive scientific research despite lack of materials and succeeded in making in Korean way a catalyst for vinyl acetate synthesis with ethylene on the basis of abundant local raw materials.
