Abstract
The present invention discloses a method for improving the total alcohol amount of geraniol, and belongs to the technical field of turpentine deep processing. The method comprises: adding 100 parts by weight of linalool, 20-25 parts by weight of boric acid pentaerythritol ester, and 5-10 parts by weight of a radium catalyst to a reaction kettle, heating to a temperature of 160-180 DEG C, stirring for 14-16 h, carrying out hydrolysis and pressure reducing rectification, and discharging the material. According to the present invention, the method has characteristics of simple process route, easy reaction control, low auxiliary raw material consumption and low cost, and the total alcohol amount of the prepared geraniol achieves more than or equal to 99.5%.
Description
Technical field
The invention belongs to turps deep process technology field, particularly relate to a kind of method improving the total alcohol amount of Geraniol.
Background technology
Geraniol, for colourless to yellow oily liquid, has gentleness, sweet Rose breath.Geraniol is the host of rose system essence, it is indispensable blending raw material in various floral compound, 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.
Existing industrial production obtains Geraniol, and its total alcohol amount is not high, is difficult to get a promotion.
Summary of the invention
The technical problem that the present invention solves is to provide the method for the total alcohol amount of a kind of raising Geraniol, and the method can solve existing production and obtain the problem that Geraniol total alcohol amount is not high, be difficult to raising.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of method improving the total alcohol amount of Geraniol is:
By weight, by 100 parts of phantols, 20 parts ~ 25 parts boric acid pentaerythritol esters, 5 parts ~ 10 parts radium catalyzer add reactor, are warming up to 160 DEG C ~ 180 DEG C, stir 14 hours ~ 16 hours, then through hydrolysis, rectification under vacuum, discharging.
In technique scheme, technical scheme is more specifically: phantol 100 parts, boric acid pentaerythritol ester 20 parts, radium catalyzer 10 parts;
Further, phantol 100 parts, boric acid pentaerythritol ester 22 parts, radium catalyzer 8 parts;
Further, phantol 100 parts, boric acid pentaerythritol ester 25 parts, radium catalyzer 5 parts.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
Present invention process route is simple, reaction is easy to control, consumption auxiliary raw material is few, cost is low, and total alcohol amount of its obtained Geraniol reaches more than 99.5%.
