CYCLOHEXYL ACETATE - Reference Information
| FEMA | 2349 | CYCLOHEXYL ACETATE |
| NIST chemical information | Information provided by: webbook.nist.gov (external link) |

| identification test | in sample 1m1, add 5ml of 10% potassium hydroxide ethanol solution, install a reflux condenser, heat in a water bath for 1h, and the original special aroma disappears. After cooling, 1ml of dilute hydrochloric acid test solution (TS-117) and 8ml of water are added, and the liquid shows acetate reaction (IT-1). Take 0.2g of sample, put it into an evaporator, add nitric acid 1 m1, heat it in a water bath for 20min, and then steam it dry on a sand bath, but do not carbonize it. After cooling, add 4ml of water and 0.5ml of sodium hydroxide test solution (TS-224) to dissolve it, then adjust it to weak acid with dilute nitric acid test solution (TS-158), then transfer it to a test tube, and add lml of silver nitrate test solution (TS-210) to produce white precipitate. When diluted nitric acid is added to adjust to strong acidity, the precipitation dissolves. |
| content analysis | determined by method 1 in ester determination method (OT-18). The amount of sample taken is 1g. The equivalent factor (e) in the calculation is 71.10. It should be determined by GT-10-4 non-polar column method. |
| toxicity | LD506730 mg/kg (rat, oral). |
| usage limit | FEMA(mg/kg): soft drink 20; Cold drink 15; Candy 100; Baked food 110. Moderate limit (FDA § 172.515,2000). |
| use | spices. Mainly used to prepare apple, banana, black spike currant, raspberry and other flavors. |
| production method | is formed by dehydration and esterification of cyclohexanol with glacial acetic acid or acetic anhydride according to the normal method. |
| category | combustible items |
| toxicity classification | highly toxic |
| acute toxicity | oral-rat LD50: 6730 microl/kg |
| stimulation data | skin-rabbit 500 mg/24 hours moderate; Eye-rabbit 500 mg/24 hours mild |
| explosive hazard characteristics | blastable when mixed with air |
| flammability hazard characteristics | combustible in case of open flame, high temperature and strong oxidant; Stimulating smoke produced by combustion |
| storage and transportation characteristics | complete packaging, light loading and unloading; warehouse ventilation, away from open flames, high temperature, separate storage from oxidant |
| fire extinguishing agent | foam, dry powder, carbon dioxide, sand |
