；

1,4- 丁二醇( 簡稱BDO) 是一種重要的有機和精細化工原料, 它被廣
泛應(yīng)用于醫(yī)藥、化工、紡織、造紙、汽車和日用化工等領(lǐng)域。由BDO 可以生產(chǎn)四氫呋喃( THF) 、聚對苯二甲酸丁二醇酯( PBT) 、γ- 丁內(nèi)脂( GBL) 和聚氨酯樹脂( PU Resin) 、涂料和增塑劑等,以及作為溶劑和電鍍行業(yè)的增亮劑等。

1,4丁二醇是一種重要的有機化工和精細化工原料，是生產(chǎn)聚對苯二甲酸丁二醇酯(PBT)工程塑料和PBT纖維的基本原料；PBT塑料是最有發(fā)展前途的五大工程塑料之一。　　1,4丁二醇是生產(chǎn)四氫呋喃的主要原料，四氫呋喃是重要的有機溶劑，聚合后得到的聚四亞甲基乙二醇醚(PTMEG)是生產(chǎn)高彈性氨綸(萊卡纖維)的基本原料。氨綸主要用于生產(chǎn)高級運動服、游泳衣等高彈性針織品。　　1,4丁二醇的下游產(chǎn)品γ-丁內(nèi)酯是生產(chǎn)2-吡咯烷酮和N-甲基吡咯烷酮產(chǎn)品的原料,由此而衍生出乙烯基吡咯烷酮、聚乙烯基吡咯烷酮等一系列高附加值產(chǎn)品，廣泛用于農(nóng)藥、醫(yī)藥和化妝品等領(lǐng)域。

發(fā)展歷史：

In its industrial synthesis, acetylene reacts with two equivalents of formaldehyde to form 1,4-butynediol, also known as but-2-yne-1,4-diol. This type of acetylene-based process is illustrative of what is known as "Reppe chemistry", after German chemist Walter Reppe. Hydrogenation of 1,4-butynediol gives 1,4-butanediol.

LyondellBasell manufactures 1,4-butanediol in a proprietary, multi-step process without the use of acetylene. First, propylene oxide is converted to allyl alcohol. The allyl alcohol is then hydroformylated to 4-hydroxybutyraldehyde. Hydrogenation of the 4-hydroxybutyraldehyde yields 1,4-butanediol.[4]

It is also manufactured on an industrial scale from maleic anhydride, which is first converted to the methyl maleate ester, then hydrogenated. Other routes are from butadiene, allyl acetate and succinic acid[5].

Genomatica (a San Diego-based company) has genetically engineered E. coli to metabolize sugar into 1,4-butanediol. They expect to build and begin operating a pilot plant by the end of 2009. Genomatica CEO Christopher Gann said the process consumes 32,000 BTU per pound of 1,4-butanediol (75 MJ/kg), far less than the acetylene-based process, and does not have any by-products.[6][7]

工業(yè)使用：

1,4-Butanediol is used industrially as a solvent and in the manufacture of some types of plastics, elastic fibers and polyurethanes. In organic chemistry, 1,4-butanediol is used for the synthesis of γ-butyrolactone (GBL). In the presence of phosphoric acid and high temperature, it dehydrates to the important solvent tetrahydrofuran.[8] At about 200 °C in the presence of soluble ruthenium catalysts, the diol undergoes dehydrogenation to form butyrolactone.[9]

World production of 1,4-butanediol is about one million metric tons per year and market price is about 2,000 USD (1,600 EUR) per ton (2005). Almost half of it is dehydrated to tetrahydrofuran to make fibers such as Spandex.[10] The largest producer is BASF.[11]
