CAS: 111-29-5
分子式: C5H12O2
分子量: 104.15
沸点: 242℃
熔点: -18℃
中文名称: 
1,5-戊二醇
英文名称: 
1,5-Pentanediol
1,5-dihydroxypentane
1,5-pentamethylene glycol
1,5-pentylene glycol
alpha,omega-pentanediol
pentamethylene glycol
pentane-1,5-diol
pentamethyleneglycol
性质描述: 无色粘稠液体。熔点-18℃,沸点238-239℃,134℃(1.6kPa),120℃(0.4kPa),相对密度0.9941(20/4℃),折光率1.4499,闪点129℃。能与水、甲醇、乙醇、殊途同归酮、乙酸乙酯混溶,25℃时醚中的溶解度为11%(重量)。味苦。
生产方法: 1.以四氢糠醛为原料,经催化加氢而得。加氢操作在高温高压下进行,反应温度300-310℃,压力为22-42MPa,工业化有一定因难可先将四氢糠醇制成二氢吡喃,再由二氢吡喃水合制5-羟基戊醛,然后经催化加氢而得到1,5-戊二醇。将二氢吡喃、水及少量盐酸加入水合釜内,于50℃反应30-40min,用氢氧化钠溶液中和反应液后进行蒸馏,先脱除水分,再收集60-64℃(0.4kPa)馏分得到5-羟基戊醛,将其加入高压釜,在镍催化剂作用下,于120-150℃、约6兆帕压力下加氢,反应结束后,减压蒸馏,收集119-120℃(0.4kPa)馏分,即为成品。2.由环戊二烯光氧化而得环氧戊烯醛,再于70-100℃、约7MPa压力催化加氢而得。
用途: 用作有机合成中间体,用于制造聚酯、聚醚和香料等。

应用
1,5-Pentanediol is used as a plasticizer in cellulose products and adhesives. It is used as a brake fluid additive. It reacts with 3,4-dihydro-2H-pyran to get 5-tetrahydropyran-2-yloxy-pentan-1-ol. It is also used to prepare polyesters for emulsifying agents and resin intermediates. Further, it is used in ink, toner and colorant products. In addition to this, it is used in brake fluid compositions.

备注
Hygroscopic. Incompatible with acid chlorides, acid anhydrides, oxidizing agents, chloroformates and reducing agents.
