파라-톨룰일산 C화학적 특성, 용도, 생산
화학적 성질
colourless crystals or white crystalline powder. Slightly soluble in water; soluble in alcohol and ether. Combustible.용도
p-Toluic Acid is used as a reagent in the synthesis of several organic compounds including that of 2-aryl-1,3,4-oxadiazole derivatives which are potential antibacterial agents. Also used in the synthesis of 4-(bromomethyl) benzoic acid.정의
ChEBI: A methylbenzoic acid in which the methyl substituent is located at position 4.공기와 물의 반응
Fine dust dispensed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard. . Insoluble in water.화재위험
Flash point data for p-Toluic acid are not available; however, p-Toluic acid is probably combustible.Purification Methods
Crystallise the acid from water, water/EtOH (1:1), MeOH/water or *benzene. [Beilstein 9 IV 1724.] Aromatic acid impurities (to <0.05%) can be removed via the (±)--methylbenzylamine salt as described for 2,4-dichlorobenzoic acid [Ley & Yates Organic Process Research & Development 12 120 2008]. The S-benzylisothiuronium salt has m 164o (from aqueous EtOH).파라-톨룰일산 준비 용품 및 원자재
