Abstract
The invention discloses a method for carrying out isosynthesis on geraniol by adopting linalool, belonging to the technical field of turpentine deep processing. The method comprises the steps of adding linalool, cinnamyl acetate, an organic tin catalyst and a vanadium compound catalyst to a reaction kettle, heating the materials to 170-190 DEG C, stirring the materials for 8-12 hours and then carrying out hydrolysis, rectification at reduced pressure and discharging. The method has the advantages of simple process, small auxiliary material utilization amount and low cost, and reactions are easy to control.
Description
Technical field
The invention belongs to turps deep process technology field, relate in particular to a kind of method of phantol isoparaffin synthesis Geraniol.
Background technology
Geraniol, to yellow oily liquid, has gentleness, sweet Rose breath for colourless.Geraniol is that rose is the host of essence, it is indispensable blending raw material in various floral compounds, be widely used in floral type daily essence, also can be used for the food flavour of the odor types such as the fruit flavour type such as apple, strawberry, Chinese cassia tree, ginger, also can be used for making ester perfume.
The method of existing industrial production Geraniol, mainly containing by the high molecular weight polyols boric acid ester taking molecular weight as 5000-10000 is reaction promoter, taking VB and group vib metal or its oxide compound as catalyzer, makes the method for the synthetic Geraniol of fragrant camphor tree isomery alcohol.But there is complex process, react shortcomings wayward, that subsidiary material consumption is many, cost is high in the method.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of method of phantol isoparaffin synthesis Geraniol, and the method can solve existing Geraniol production method and have complex process, reacts problems wayward, that subsidiary material consumption is many, cost is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of method of phantol isoparaffin synthesis Geraniol is:
By the phantol of 0.8 weight part～1.0 weight part, the cinnamyl acetate of 0.6 weight part～0.8 weight part, the vanadium compound catalyzer of the organotin catalysts of 0.002 weight part～0.004 weight part and 0.004 weight part～0.01 weight part adds in reactor, be warming up to 170 DEG C～190 DEG C, stir 8 hours～12 hours, then through hydrolysis, rectification under vacuum, discharging;
Further, described organotin catalysts is the one in dibutyltin dilaurate, stannous octoate, dibutyltin diacetate three.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
1. operational path of the present invention is simple, reaction is easy to control, consumption subsidiary material are few, cost is low, and total alcohol amount of its Geraniol making reaches more than 98%.
2. the cinnamyl acetate itself that the present invention uses has the fragrance of a flower of gentle sweet taste, can effectively improve the flavouring essence quality of Geraniol product, compares other synthetic method product fragrance stronger.
