Chemical properties: sublimation of white crystalline with lemongrass aroma and slightly savory rhyme medicine. Insoluble in water, soluble in water, alcohol, ether, chloroform.
Activity: anti-tumor; anti-bacterial (E. coli); antifungal; anticoagulant effect; hypoglycemic (rat); larvicides (housefly larvae)
Usage:
1.Coumarin was found in 1820 in the tonka bean. Coumarin in the form of glycosides present in many plants. It has a strong scent of tonka bean, also has a new treasure and sweet chocolate flavor, fragrant long. The aroma of fresh hay in large part due to the new mowing drying process, glycosides during fermentation and decomposition caused by the release of coumarin. Coumarin used to make perfume. Mowing type commonly used in the preparation of the new type and fougere perfumes. And violet, sunflower, chypre, hawthorn flowers, orchids, lavender and other flavors. It can be used together with vanillin candy, cakes and the like have flavor, add tobacco to increase natural flavors. Join coumarin in galvanized (or Cd, Ni) plating solution, the coating can be reduced from the hole, increase the brightness. Coumarin is the manufacture of other spices and a variety of other chemical raw materials. Coumadin is a derivative of the parent category. Some of these derivatives exist in nature, others by synthetic methods.
2.For the manufacture of perfumes as a fixative agent, also used in electroplating industry
3.Perfume and soap for manufacturing
4.Lactones synthetic fragrances. Mainly used as violet, sunflower, chypre, hawthorn blossom, orchid, lavender, new grass and Liu Fu Singular other flavors of blending spices.
Brief manufacture process:
Equipped with a distillation unit, 250mL three-necked flask dropping funnel and a thermometer was added 95% salicylaldehyde 40g, freshly distilled acetic anhydride and 73g of anhydrous potassium acetate treated 1g, then heated up, three inner temperature control in 145 ~ 150 ℃, steam temperature control below 120 ℃. In this case, acetic acid began to distill. When steamed about 15g, the start dropping 15g of acetic anhydride and acetic acid should be dropping its distilled at a fairly. After completion of the addition of acetic acid, separated some time, found difficult to control the temperature at 120 ℃, it can continue to raise the internal temperature to about 208 ℃, and maintain 15min to half an hour, and then allowed to cool.
When the temperature is cooled to about 80 ℃, stirring, washed with hot water and let stand aqueous layer was separated oil with 10% sodium carbonate solution to neutralize, was slightly alkaline, neutral and then washed with hot water to remove the aqueous layer, the reservoir vacuum distillation, collecting 150 ~ 160 ℃ / 1866Pa fraction of a crude product. The crude product was 95% by mass ethanol (ethanol and crude product ratio of 1: 1 and recrystallized to give a white granular crystals, coumarin pure
