1-(2,3,4-트리하이드록시페닐)프로판-1-온 C화학적 특성, 용도, 생산

제조 방법

Preparation by acylation of pyrogallol with propionic acid
in the presence of boron trifluoride in ethyl ether for 1 h at 0° (80%)
in the presence of Amberlite IR-120 (cation exchange resin sulfonic acid ? type) at 160° for 2–3 h (78%)
Zeokarb 225 was found to be as effective
in the presence of zinc chloride, at 130–140° for 90 min (Nencki ? reaction) (35%)
in the presence of 70% perchloric acid at reflux for 1 h (33%)
Preparation by reaction of propionyl chloride with pyrogallol and heating 4 h on a water bath (75%)
Preparation by acylation of pyrogallol with propionic anhydride
in the presence of Amberlite IR-120 (cation exchange resin sulfonic acid type) ? at 160° for 2–3 h (79%)
Zeokarb 225 was found to be as effective
in the presence of concentrated sulfuric acid (small drops) at 130° for some ? min (65%)
in the presence of zinc chloride, but using a mixture of propionic acid/propionic ? anhydride (85/100) at 135–140° for 40 min, then at r.t. overnight (59%).
