Abstract
The invention discloses a method for preparing a catalyst composition for producing isolongifolene and belongs to the technical field of preparation of forestry chemical products. The method comprises the steps: firstly, putting zirconia and silica into 98% concentrated sulfuric acid for acidifying for 1 hour; then, drying at the temperature of 50-55 DEG C, and then, calcining for 4 hours at the temperature of 550-600 DEG C; and finally, uniformly mixing the calcined material with cation exchange resin while the calcined material is hot, thereby preparing the catalyst composition. By applying the catalyst composition prepared by the method to the production of isolongifolene, the yield of isolongifolene can be effectively increased, and thus the production cost of isolongifolene is reduced.
Description
Technical field
The invention belongs to silvichemical preparing technical field, particularly relate to a kind of preparation method of isolonglifolene production carbon monoxide-olefin polymeric.
Background technology
Isolonglifolene is through catalytic isomerization products therefrom by the longifolene in heavy turpentine, the same with longifolene is also a kind of sesquiterpene, be a kind of novel raw material in synthetic perfume industry, the spices such as isolongitolanone, Isolongifolenone, isolonglifolene alcohol, isolongifolenyl acetate, amborol can be synthesized; Itself there is banksia rose fragrance, with being widely used in modern synthetic perfume industry.
At present, the yield of the isolonglifolene obtained according to conventional synthetic method is not very high always, and this makes the production cost of isolonglifolene remain high always.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of preparation method of isolonglifolene production carbon monoxide-olefin polymeric, by carbon monoxide-olefin polymeric obtained for the method for the production of isolonglifolene, can effectively improve its yield, thus reduce its production cost.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
Raw material is made up of the component of following weight portion:
30 parts ~ 45 parts cationic ion-exchange resins, 30 parts ~ 35 parts zirconias, 10 parts ~ 15 parts silica and 50 parts ~ 60 part 98% concentrated sulfuric acids;
Its preparation method comprises the following steps:
A, by above-mentioned parts by weight, zirconia, silica are put into 98% concentrated sulfuric acid acidifying 1 hour;
B, at 50 DEG C ~ 55 DEG C, carry out drying by under the zirconia after step A acidification, silica, and then carry out calcining 4 hours at 550 DEG C ~ 600 DEG C;
C, the zirconia after step B calcination processing, silica are mixed with cationic ion-exchange resin while hot obtained.
In technique scheme, technical scheme is more specifically: 30 parts of cationic ion-exchange resins, 35 parts of zirconias, 12 parts of silica and 50 part of 98% concentrated sulfuric acid;
Further, 45 parts of cationic ion-exchange resins, 32 parts of zirconias, 10 parts of silica and 55 part of 98% concentrated sulfuric acid.
Further, 40 parts of cationic ion-exchange resins, 30 parts of zirconias, 15 parts of silica and 60 part of 98% concentrated sulfuric acid.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
By inventive catalyst composition for the production of isolonglifolene, can effectively improve its yield, thus reduce its production cost.
