摘要
用C5以上的多碳醇及环己醇、苄醇、异丁醇、叔醇(3-甲基-3-庚醇)和混合醇(正戊醇+仲戊醇)还原VOPO42H2O制备VOHPO40.5H2O。讨论了不同多碳醇与VOPO42H2O作用机理及对VOHPO4O.5H2O不同晶面生长的影响。伯醇有利于VOHPO4O.5H2O(220)晶面的生长;仲醇有利于(001)晶面生长;苄醇、环己醇、叔醇的还原性质与仲醇相似;异丁醇对VOHPO40.5H2O(001)和(220)晶面的生长无影响。
Precursor VOHPO 4·0 5H 2O has been prepared by reducing VOPO 4·2H 2O with 1 and 2 C 5~10 straight chain alcohols such as benzyl alcohol,cyclohexanol,3 methyl 3 enanthol and isobutanol The principle of reacting VOPO 4·2H 2O with different alcohols and the influence on the growth of crystal face of VOHPO 4·0 5H 2O have been discussed Precursors prepared from 1 alcohols comprise VOHPO 4·0 5H 2O crystals for which the (220) reflection is virtually the only feature of the diffraction pattern;whereas precursors prepared from 2 alcohols give VOHPO 4·0 5H 2O crystals for which the (001) reflection is the dominant feature of the diffraction pattern Precursors prepared from benzyl alcohol,cycloheanol,3 methyl 3 enanthol are the same as 2 alcohol Precursor prepared from isobutanol gives VOHPO 4·0 5H 2O crystal for which reflection is not the feature of diffraction pattern
