- Synthesis method of tert-butyl cyclohexyl ethyl carbonate spice
-
The invention discloses a synthesis method of tert-butyl cyclohexyl ethyl carbonate spice and relates to the technical field of fine chemical engineering. The synthesis method includes: using phenol and tert-butanol as starting raw materials for alkylation reaction, hydrogenating, being in acetylation reaction with diethyl carbonate to generate tert-butyl cyclohexyl ethyl carbonate. The synthesismethod is easy-to-get in raw material and high in yield, a ratio of o-tert-butyl phenol and p-tert-butyl phenol generated by reaction of phenol and tert-butanol reaches 7:3, and p-tert-butyl phenol which is a byproduct can generate iris ester for use after being hydrogenated and esterified; the spice is high in purity and pure and gentle in fragrance and meets flavoring requirements of essence andspice.

- Production method of tertiary butyl cylcohexyl ethyl carbonate synthetic perfume
-
The invention discloses a production method of a tertiary butyl cylcohexyl ethyl carbonate synthetic perfume and relates to the technical field of fine chemical production. The production method provided by the invention comprises the following steps of by taking phenol and tert-butyl alcohol as starting materials to perform alkylation reaction, then performing hydrogenation on a reactant, and performing acetylation reaction on the reactant and diethyl carbonate to produce tertiary butyl cylcohexyl ethyl carbonate, wherein the raw materials are available, the yield is high, the proportion of o-tert butylphenol produced by reaction of the phenol and the tert-butyl alcohol and p-tert-butylphenol reaches 7 to 3, an iris ester product can be obtained after performing hydrogenation and esterification on the p-tert-butylphenol as a by-product and is put to use. The production method is strong in controllability of technological parameters, good in repeatability and simplified in operation; and a product is high in purity, pure and gentle in fragrance and accords with the flavor blending requirements for an essence perfume.
