Abstract
The present invention discloses the preparation method of a kind of high-purity isolonglifolene, belongs to Colophonium deep process technology field.The present invention uses the raw material of following weight portion: longifolene 100 parts, 1 part～5 parts of vinyl chloride, vinyl acetate 1 part～5 parts, 2 amino 2 methyl 1 propanol 0.5 part～1 part and modified aluminium triphosphate 0.1 part～0.2 part；Put into mix homogeneously in reactor, and insulation reaction 0.5 hour～1 hour at 65 DEG C～75 DEG C including by above-mentioned raw materials longifolene, vinyl chloride, vinyl acetate, 2 amino 2 methyl 1 propanol and modified aluminium triphosphate, then distill.The purity of the product isolonglifolene that the present invention prepares reaches more than 96%.
Description
Technical field
The invention belongs to Colophonium deep process technology field, the preparation method of a kind of high-purity isolonglifolene.
Background technology
Isolonglifolene, the same with longifolene, also it is a kind of sesquiterpene, is a kind of novel former in synthetic perfume industry
Material, can synthesize the perfume (or spice) such as isolongitolanone, Isolongifolenone, isolonglifolene alcohol, isolongifolenyl acetate, amborol
Material；Itself there is Radix Aucklandiae fragrance, with being widely used in modern synthetic perfume industry.Although isolonglifolene has
Above-mentioned advantage, but there is some shortcomings, the purity of the product isolonglifolene that the most traditional preparation method prepares is the most inadequate
Height, thus limit the popularization of application.
Summary of the invention
The present invention provides the preparation method of a kind of high-purity isolonglifolene, and it is high that the terpene resin that the method prepares has purity
Advantage.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
Use the raw material of following weight portion:
Longifolene 100 parts, 1 part～5 parts of vinyl chloride, vinyl acetate 1 part～5 parts, 2-amino-2-methyl-1-propanol 0.5 part～1
Part and modified aluminium triphosphate 0.1 part～0.2 part；
Comprise the following steps:
Above-mentioned raw materials longifolene, vinyl chloride, vinyl acetate, 2-amino-2-methyl-1-propanol and modified aluminium triphosphate are thrown
Enter mix homogeneously in reactor, and insulation reaction 0.5 hour～1 hour at 65 DEG C～75 DEG C, then distill.
Owing to using technique scheme, there is advantages that
The purity of the product isolonglifolene that the present invention prepares reaches more than 96%.
Detailed description of the invention
Below in conjunction with instantiation, the invention will be further described:
The preparation method of embodiment 1--isolonglifolene:
By longifolene 100kg, vinyl chloride 1kg, vinyl acetate 1kg, 2-amino-2-methyl-1-propanol 1kg and modified trimerization phosphorus
Acid aluminum 0.2kg puts into mix homogeneously in reactor, and insulation reaction 1 hour at 65 DEG C, then distills.
The purity of the product isolonglifolene that the present embodiment prepares is 96.1%.
The preparation method of embodiment 2--isolonglifolene:
By longifolene 100kg, vinyl chloride 5kg, vinyl acetate 5kg, 2-amino-2-methyl-1-propanol 0.5kg and modified trimerization
Aluminum phosphate 0.1kg puts into mix homogeneously in reactor, and insulation reaction 0.5 hour at 75 DEG C, then distills.
The purity of the product isolonglifolene that the present embodiment prepares is 96.5%.
The preparation method of embodiment 3 isolonglifolene:
By longifolene 100kg, vinyl chloride 4kg, vinyl acetate 4kg, 2-amino-2-methyl-1-propanol 0.6kg and modified trimerization
Aluminum phosphate 0.15kg puts into mix homogeneously in reactor, and insulation reaction 0.5 hour at 70 DEG C, then distills.
The purity of the product isolonglifolene that the present embodiment prepares is 97%.
