KH Neochem Co., Ltd

KH Neochem Co., Ltd. manufactures chemical materials across three core areas: basic chemicals, performance materials, and electronic materials. Its product lineup includes alcohols, esters, diols, oxygenated solvents, synthetic fatty acids, and high-purity materials for industrial applications. Products include butyl acetate and ethyl acetate for coatings, printing inks, adhesives, reaction processes, and extraction; glycol ethers for coatings, inks, detergent ingredients, and brake-oil additives; and isononanol for plasticizer, resin, lubricant, surfactant, and additive production. The company also supplies 1,3-butylene glycol for inks, toiletries, cosmetics, pharmaceuticals, agricultural chemicals, polymers, and cleaning agents.

The company uses oxo reaction, also known as hydroformylation, alongside organic synthesis, purification, and quality-control technologies. Its oxo process produces aldehydes from olefins, carbon monoxide, and hydrogen, which can be converted into alcohols, synthetic fatty acids, esters, and other derivatives. High-pressure oxo facilities support production of specialty alcohols and synthetic fatty acids, including isononanol, tridecanol, and isononanoic acid. Distillation-based purification and ultratrace metal analysis support materials supplied for liquid-crystal-display and semiconductor applications. The company began industrial acetone and butanol production from molasses in Japan in 1948 and adopted its current name in 2012.
