Inhibitor for growth of auxiliary species cedar wood based on Castanopsis kawakamii litter extract liquid

The invention relates to an inhibitor for growth of auxiliary species cedar wood based on Castanopsis kawakamii litter extract liquid. The preparation method comprises the following steps: crushing and grinding Castanopsis kawakamii litter (including branches, leaves, peels and shells), adding a proper amount of distilled water into the raw materials, soaking the raw materials for 48 hours at normal temperature, and filtering the liquid by using clean gauze; finally, filtering the filtrate via a vacuum pump to obtain four 1:5 extraction solutions of branches, leaves, peels and fruits, which are determined as stock solutions; adding distilled water into the stock solution for diluting the stock solution by 1 time, 5 times, 9 times and 19 times to prepare four types of extracting solutions with different concentrations of 1:10, 1:30, 1:50 and 1:100; and treating cedar wood seeds by using the extracts with different concentrations. The result shows that the leaf extract is easily available, and the inhibition effect is more obvious than that of other litters; experiments show that the leaf extract with the concentration of 1:5 has the strongest inhibition effect, but can maintain normal vital signs of China fir; therefore, the product is a good seedling inhibitor, and is safe, environment-friendly and pollution-free to the environment.

Method for preparing methyl cedryl ether from Chinese fir oil

The invention discloses a method for preparing methyl cedryl ether from Chinese fir oil. The method comprises the following steps: by taking Chinese fir oil as a raw material, reacting the separated Chinese fir alcohol with benzyl sodium to obtain Chinese fir alcohol sodium, and reacting for 1-1.5h, wherein the molar ratio of the benzyl sodium to the Chinese fir alcohol is (1.0-1.6):1, the volume ratio of a solvent methylbenzene to the Chinese fir alcohol material in the reaction product is (2-3):1; carrying out methylation on the Chinese fir alcohol sodium and dimethyl sulfate, wherein the molar ratio of the dimethyl sulfate to the dimethyl sulfate is (1-1.2):1; reacting at 60-80 DEG C for 2.4-2.6h, and washing the reaction product by using 10% sodium bicarbonate solution, standing and layering, washing an oil layer to neutral by using 10% sodium chloride solution, and then distilling to obtain the methyl cedryl ether. Compared with a sodium hydride method and a sodium amide method, the method is mild in reaction condition, high in product yield, and pure in fragrance, the methyl cedryl ether prepared from cedar wood oil as a raw material can be replaced with the prepared methyl cedryl ether, and the situation of shortage of cedar wood oil resources can be relieved.
