杂醇油

1.主要用作溶剂，用于制药、植物提取、彩印、胶粘剂生产中，也用作染料、颜料稀释剂。

2.杂醇油直接使用不多，常用乙酸酯化作涂料用溶剂和醋酸纤维素类合成树脂的制造。其128~132℃馏分经乙酸酯化后可用作涂料、硝基喷漆、清漆、樟脑等的溶剂和香料、赛璐珞的制造原料。另外，与二硫化碳反应所得的异戊基黄原酸钾盐或钠盐，可作有色金属的浮选剂。

1.杂醇油是发酵法生产酒精的副产品。由白氨酸、异白氨酸等蛋白质分解物经酵母作用生成。其中含有异戊醇45%，异丁醇10%，旋光性戊醇5%，丙醇1.2%。此外尚含有乙醇、水及少量的丁醇、戊醇、己醇、庚醇和微量的醛、酸、酯、吡啶、生物碱等。粗制杂醇油经化学处理和精馏后，含异戊醇85%，旋光性戊醇15%。

精制方法 为除去其中的水分，可加入40%的食盐搅拌，静置一夜，盐析脱水后分馏。所得杂醇油收率为85%。若要得到纯度高的戊醇组分，可加入浓氢氧化钠溶液，使pH值达8.0~8.2，分出醇后再蒸馏，收集129~132℃的馏分。

Bio-ethanol dehydration to ethylene is an attractive alternative to oil-based ethylene. The influence of fusel, main byproducts in the fermentation process of bio-ethanol production, on the bio-ethano...

Fusel alcohols regulate translation initiation by inhibiting eIF2B to reduce ternary complex in a mechanism that may involve altering the integrity and dynamics of the eIF2B body.

Mol. Biol. Cell 21 , 2202-16, (2010)

Recycling of eIF2-GDP to the GTP-bound form constitutes a core essential, regulated step in eukaryotic translation. This reaction is mediated by eIF2B, a heteropentameric factor with important links t...
