Embodiment 1

[0025] Embodiment 1: the method for preparing muscone from garlic fruit oil, purifying neural nucleic acid from garlic fruit oil, concrete steps and raw material usage are shown in the following table:

[0026]

[0027]

[0028] Note: The refining step is to send the upper ether liquid after the methylation reaction into the refining reaction kettle,

[0029] see figure 1 And table 1, the quality of raw material is expressed as above, concrete steps are as follows:

[0030] Step 1: a. Saponification: Add lye with a concentration of 10% into the reaction tank, then add garlic fruit oil into the reaction tank, stir, feed steam and heat to 70-80°C, continue to add lye until the oil b, degreasing: cooling the saponified liquid, adding ether to extract the saponified liquid, standing still, separating the upper ether liquid, reclaiming the ether, discarding the residual oil, and leaving the saponified salt liquid; c, acid analysis: add the saponified salt solution to the ac...

Abstract

The invention discloses a method for preparing muscone by malania oleifera oil. The method disclosed by the invention has the benefits that malania oleifera rich in nervonic acids is adopted as a raw material, the nervonic acids are purified firstly, and then the muscone is obtained through ozonization, esterification, cyclization, reduction, condensation, bromination, debromination, hydrolysis, methylation and refining; the comprehensive yield of the muscone is 60 percent or above; when the method disclosed by the invention is used for preparing cyclopentadecanone, the yield is 73 percent or above, so that the method is superior to a process for preparing the cyclopentadecanone in the prior art; in the production process, by-product pelargonic acids can also be used as raw materials for modulating aviation lubricating oil. The method disclosed by the invention is high in yield, good in benefits and low in cost and overcomes the defects of lower yield, higher cost and more pollutants in an existing technology production process; solvents used in the reaction process are reagents with low boiling point and easiness in recovery, and are free from heavy metals and pollutants difficult to remove and recyclable, so that the environmental pollution is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical synthesis, in particular to a method for preparing muscone from garlic fruit oil. Background technique [0002] Muscone Muscne, scientific name 3-Methycyciopentadecanone (3-MethyCyciopentadecanone), exists in natural musk, its physical and chemical properties are colorless viscous liquid or crystal block, melting point is 33°C, boiling point is greater than 300°C, 128°C / 160pa, Musk has the functions of stimulating the central nervous system, respiratory center and heart, and promoting the secretion of various glands in the human body. It is an important drug for first aid and treatment of coma. It can expand coronary arteries, increase arterial flow, treat coronary heart disease, promote blood circulation, and reduce swelling. , pain relief and other medicinal effects. It can unblock the meridians, open the meridians, penetrate the muscles and bones. It is famous for treating stroke, middle-qi, ...
