Embodiment 1

[0012] The production method of embodiment 1--isolongifolenone:

[0013] Adopt the raw material of following weight part:

[0014] 100 parts of isolongifolene, 1 part of cobalt acetate, 1 part of modified aluminum tripolyphosphate and 0.5 part of 2-amino-2-methyl-1-propanol;

[0015] Include the following steps:

[0016] Put the above-mentioned raw materials isolongifolene, cobalt acetate, modified aluminum tripolyphosphate and 2-amino-2-methyl-1-propanol into the reaction kettle, mix them evenly, feed oxygen, and keep warm at 65°C for 8 hours, followed by filtration, distillation, crystallization, and suction filtration.

[0017] Compared with the traditional production method, the period required for the production of the product isolongifolenone in the present invention is shortened by 24 hours.

Embodiment 2

[0018] The production method of embodiment 2--isolongifolenone:

[0019] Adopt the raw material of following weight part:

[0020] 100 parts of isolongifolene, 5 parts of cobalt acetate, 5 parts of modified tripolyphosphoric acid and 1 part of 2-amino-2-methyl-1-propanol;

[0021] Include the following steps:

[0022] Put the above-mentioned raw materials isolongifolene, cobalt acetate, modified aluminum tripolyphosphate and 2-amino-2-methyl-1-propanol into the reaction kettle, mix them evenly, feed oxygen, and keep warm at 75°C for 5 hours, followed by filtration, distillation, crystallization, and suction filtration.

[0023] Compared with the traditional production method, the period required for the production of the product isolongifolenone in the present invention is shortened by 23 hours.

Embodiment 3

[0024] The production method of embodiment 3-isolongifolenone:

[0025] Adopt the raw material of following weight part:

[0026] 100 parts of isolongifolene, 4 parts of cobalt acetate, 4 parts of modified aluminum tripolyphosphate and 0.8 part of 2-amino-2-methyl-1-propanol;

[0027] Include the following steps:

[0028] Put the above-mentioned raw materials isolongifolene, cobalt acetate, modified aluminum tripolyphosphate and 2-amino-2-methyl-1-propanol into the reaction kettle, mix them evenly, feed oxygen, and keep warm at 70°C for 6 hours, followed by filtration, distillation, crystallization, and suction filtration.

[0029] Compared with the traditional production method, the period required for the production of the product isolongifolenone in the present invention is shortened by 22 hours.

Abstract

The invention discloses a production method of isolongifolene ketone, and belongs to the technical field of deep processing of colophony. The isolongifolene ketone comprises the following raw materials in parts by weight of 100 parts of isolongifolene, 1-5 parts of cobalt acetate, 1-5 parts of modified aluminum tripolyphosphate, and 0.5-1 part of 2-amino-2-methyl-1-propanol. The production method comprises the following steps of adding the isolongifolene, the cobalt acetate, the modified aluminum tripolyphosphate and the 2-amino-2-methyl-1-propanol to a reaction kettle to be uniformly mixed, leading oxygen, performing a heat preservation reaction at 65-75 DEG C for 5-8 hours, then performing filtration, performing distillation, performing crystallization, and performing sucking filtration. Compared with a conventional production method, the production method disclosed by the invention has the advantage that the production cycle for producing the product namely the isolongifolene ketone is shortened by 20 hours or above.

Description

technical field [0001] The invention belongs to the technical field of rosin deep processing, in particular to a production method of isolongifolenone. Background technique [0002] Isolongifenone is an important sesquiterpenes, and it is a very valuable spice. It has a strong sweet, woody, amber aroma and a slight camphor smell. Its derivatives are widely used in the industry. It has been used as a fragrance substance in perfumes, space sprays, cosmetics, detergents, deodorants, fabrics, fiber products and paper products, etc. In addition, isolongifolenone and its derivatives have been found to effectively inhibit the activity of tyrosinase, and are used to treat some skin pigmentation disorders caused by excessive melanin. In addition, saturated isolongifolenone has been used as a bridging core structure to prepare chiral estrogen receptors for the regulation of fertility, the prevention and treatment of breast cancer, and the replacement of menopausal hormones.
