| Overview | 2-ethoxy-5-(1-propenyl) phenol is a very important organic chemical raw materials, widely used in chemical, chemical, pharmaceutical, food, materials and other fields. It can be used for the manufacture of phenolic resin, after separation and purification can be used as bactericide, disinfectant, is a perfume, fuel, drug intermediates, for the synthesis of medicine, dyes, rubber antioxidant, monomer inhibitor, petroleum anticoagulants, etc. Therefore, the catalytic hydrogenolysis of lignin to produce phenolic compounds will bring great benefits and is of great significance. |
| Use | GB 2760-1996 specifies temporary use of flavorants. Mainly used as a substitute for vanillin and the preparation of chocolate flavor. |
| method of production | alkaline production of 1-ethoxy-2-methoxy-4-propenyl benzene in ethanol or methanol solution at 150-190 °c and pressurized formed by hydrolysis; or in ethylene glycol solution under normal pressure and heat hydrolysis. It is derived from 1-ethoxy-2-methoxy-4-propenylbenzene as a raw material by saponification and double bond shift. |
