trans-p-クマル酸 化学特性,用途語,生産方法
外観
白色〜うすい黄褐色又は緑青色, 結晶〜結晶性粉末
用途
有機合成原料。
化学的特性
Off-white to beige or greenish powder. Soluble in alcohol, ether and hot water, slightly soluble in benzene, insoluble in petroleum ether.
製造方法
Synthesis of p-Coumaric acid: take o-acetylsalicyloyl chloride as raw material, in the presence of magnesium chloride, react with diethyl malonate in acetonitrile solvent, then add triethylamine, and react at 0°C for 1 h to obtain ( 2-acetoxybenzoyl) diethyl malonate product, then heated to 50°C in potassium hydroxide/methanol solution, reacted for 3h, and cyclized to obtain p-Coumaric acid.
主な応用
trans-4-Hydroxycinnamic acid is used as a hydroxycinnamic acid with antioxidant properties. p-Coumaric acid is an aromatic phytochemical for proteomics research. It has been used as a component of chemiluminescent substrate for protein detection in western blotting.
定義
ChEBI: p-coumaric acid is the trans-isomer of 4-coumaric acid. 4-coumaric acid is a coumaric acid in which the hydroxy substituent is located at C-4 of the phenyl ring. It has a role as a plant metabolite. It is a conjugate acid of a 4-coumarate.
純化方法
Crystallise p-coumaric acid from H2O (charcoal). It forms needles from concentrated aqueous solutions as the anhydrous acid, but from hot dilute solutions the monohydrate acid separates on slow cooling. The acid (33g) has been crystallised from 2.5L of H2O (1.5g charcoal) yielding 28.4g of recrystallised acid, m 207o. It is insoluble in *C6H6 or pet ether. The UV in 95% EtOH has max 223 and 286nm ( 14,450 and 19000 M-1cm-1). [UV Wheeler & Covarrubias J Org Chem 28 2015 1963, Corti Helv Chim Acta 32 681 1949, Beilstein 10 IV 1005.]
