20637-09-6 - Reference Information
| Chemical properties | Needle crystals. Melting point 42 ℃. |
| use | organic chemical raw material intermediates. |
| Production method | It is obtained by esterification of 4-(p-aminobenzene) butyric acid and methanol. In a dry reaction pot, add methanol, add p-aminobenzobutyric acid and hydrogen chloride methanol solution under stirring, and heat and reflux for 3 hours. Retract methanol under reduced pressure to dry, and precipitate methyl ester hydrochloride. Add ice water to dissolve, activated carbon to decolorize and filter. The obtained filtrate is adjusted to pH 8 with sodium hydroxide solution, and 4-(p-aminobenzene) methyl butyrate is precipitated. |
