关于1,3-丙二醇的市场前景及医药应用

目前国内1,3-丙二醇主要应用在医药中间体,其他方面很少应用,用量非常小,但不知道未来是否有广阔的市场前景,另外在医药方面1,3-丙二醇主要合成什么样的药品,医药方面是否有发展前景

2001年世界1,3-丙二醇的生产能力约14万吨/年,生产厂家仅有美国Shell公司、DuPont公司和德国的Degussa公司。2001年世界PTT需求量为20万吨左右, 1,3-丙二醇需求量为7.2万吨。据壳牌公司预计,到2010年包括非纤维应用在内,世界PTT的年需求量将达到100万吨,需1,3-丙二醇36万吨。其中近45%应用于地毯,50%以上用于其它纺织领域。业内专家指出PTT纤维将是21世纪重点发展的新型纤维,将成为最流行的纤维品种之一。

近年来国外1,3-丙二醇和PTT生产以及技术开发的高速发展,已经引起国内有关生产厂家和科研单位的高度重视。预计到2010年我国化纤地毯的需求量将达到5000-6000万m2,需各种化纤原料290-350万吨,如10%的化纤地毯原料以PTT来代替,约需PTT 29-35万吨,折1,3-丙二醇的需求量为10.4-12.6万吨。

1,3-丙二醇现在主要用于生产新型热塑性聚酯,即聚对苯二甲酸丙二醇酯(PTT)。1,3-丙二醇是国内外生产和技术开发的热点产品,其下游产品PTT可以部分取代尼龙,竞争力强,有非常广阔的市场前景。
