The preparation method of nerol ether

Abstract

The invention discloses a preparation method of nerolin. In order to overcome the defects that an existing preparation method of the nerolin has many byproducts, low product purity and limited production application, the preparation method comprises the following steps: generating nerol peroxide by carrying out photosensitized oxidation on nerol; recycling a solvent; reducing the nerolin peroxide into dinerol; inducing the dinerol by acid to generate nerolin; and purifying the nerolin. The preparation method is used for preparing nerolin, and is high in raw material conversion ratio, short in process route, gentle in reaction condition, energy-saving and environment-friendly, few in byproduct and high in product purity, so that an applied range of the nerolin is expanded, and the benefits are remarkably improved. According to the test and detection results, the mass fraction of the nerolin is 96%-98.5%, and the yield of the nerolin is 78-83.5%.

Description

technical field

[0001] The invention relates to a preparation method of daily spices, in particular to a preparation method of nerolidol with nerol as the main raw material. Background technique

[0002] Nerolido is naturally present in pomelo juice, white wine, rose oil, and geranium oil. It is a raceme and has a strong floral aroma, a scent like neroli oil, and a fresh green scent. Colorless to yellow liquid, insoluble in water, soluble in ethanol and other organic solvents, with high application value, widely used in the preparation of medicinal herbs, vegetables, cucumbers, tropical fruits, tea and other food flavors.

[0003] The method for producing nerolidol abroad mainly takes nerolidol as raw material and uses peroxide to oxidize. In this method, there are many by-products and low product purity, so the range of application of the product is limited. Therefore, it is of great significance to develop a green synthesis process of nerolithin and obtain high-purity ner...
