| titleOfInvention | A kind of synthesis technique of L menthols |
| abstract | The present invention relates to perfume synthesis field, and in particular to a kind of synthesis technique of L menthols, comprises the following steps：D, l menthol synthesize；D, l menthol rectifying；D, l menthol are esterified；Benzoic acid d, l menthyl ester rectifying；Benzoic acid d, l menthyl ester are split；D menthols synthesize；Menthol closes isomerization；L menthols synthesize.The present invention from chemical products Thymol simple and easy to get and cheap be raw material; optimize enzymatic synthesis condition, the rectifying in esterification, promote esterification to being advantageous to generate benzoic acid d; l peppermints acid aspect changes; esterification yield is improved, and combines benzoic acid d, l menthyl ester optimization crystallization fractionation technology; preparing L menthols using this method has high income; cost is low, easy to operate, the features such as being suitable for serialization, large-scale production.The synthesis technique, total system enclosed formula circulate operation, no waste water, energy-conserving and environment-protective. |
