| Application | dibenzyl ether can be used as a toughening agent for nitrocellulose and a solvent for the preparation of flavors, it can also be used as a medium-level antioxidant. It can also be used as a solvent for cellulose nitrate, a plasticizer for cellulose acetate, a resin, a rubber, a wax, an artificial musk, and the like. The mixture of dibenzyl ether and zinc oxide is a repellent for mosquitoes, flies, flies and fleas. |
| preparation method | dibenzyl ether can be obtained from the reaction of benzyl chloride with concentrated alkali, and is also a by-product in the production of benzyl alcohol. |
| content analysis | The measurement was performed by a method using a non-polarized column in gas chromatography (GT-10-4). |
| toxicity | GRAS(FEMA). LD502500 mg/kg (rat, oral). |
| usage limit | FEMA(mg/kg): Soft drink 8.3; Cold drink 5.6; Candy 23; Baked goods 25; pectin 85~160. Moderate limits (FDA § 172.515,2000). |
| Use | flavor. Mainly used for the preparation of mushrooms and cherry flavor. used as gas chromatography stationary liquid and nitrocellulose plasticizer, also used in the preparation of spices used as a medium level antioxidant, mainly used in the manufacture of sponge rubber products, can also be used for the preparation of spices |
| production method | a by-product from the hydrolysis of benzyl chloride to produce benzyl alcohol, such as the replacement of carbonate with concentrated alkali in this reaction, the yield can then be increased to 50% or more. |
