3142-72-1 - Reference Information
| FEMA | 3195 | 2-METHYL-2-PENTENOIC ACID |
| freezing point | 20.0 to 25.0 ℃ |
| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| content analysis | accurately weigh about 2.0g of sample, move into a 250ml triangular flask containing 75-100ml of water, add phenolphthalein test solution (TS-167), and titrate with 0.5mol/L NaOH. 0.5mol/L NaOH solution per ml is equivalent to 57.02mg of 2-methyl-2-pentenoic acid. |
| toxicity | GRAS(FEMA). |
| use limit | FEMA(mg/kg): candy, baked goods, condiments, meat and meat sausage, soup, 1.0. |
| use | GB 2760-1996 specified as allowed edible spices. Used in flavors such as strawberries, cheese, raspberries and tropical fruits. this product has fresh strawberry aroma, rich and mellow flavor and long-lasting, and is used to mix edible strawberry essence. used to prepare edible flavors such as strawberries and hawthorn |
| production method | the oxidation method of 2-methyl-2-pentenal is generally adopted. silver nitrate can be used as the oxidant, but silver nitrate consumes a lot, accounting for about 3/5 of the cost of raw materials. Propionaldehyde is formed by its own condensation in the presence of dilute alkali and then catalytic oxidation. |
