摘　　要：20 0 2年 ,我国共有 16家对羟基苯甲酸(PHBA)生产企业 ,总生产能力为 1 7万t/a,产量6 0 0 0t,其中 2 /3用于出口。预计到 2 0 0 5年 ,我国PH BA生产能力为 1 0 3万t/a即可满足内需及出口。目前以苯酚为原料生产PHBA的方法主要有两种 :柯尔伯·施密特合成法和莱默尔 蒂曼合成法。PHBA主要用于医药、化妆品及电子等行业 ,预计 2 0 0 5～ 2 0 10年 ,国内PHBA需求量的年均增长率为 11 4 %。In 2002, there were 16 manufacturers of p-hydroxybenzoic acid (PHBA) in China with total capacity of 17000t/a and output of 6000t, two thirds of which was for exports. China′s total capacity of PHBA is expected to be 10300t/a in 2005, which is enough to meet demand at home and abroad. At present, there are two manufacturing methods of PHBA based on phenol: Kolbe Schmith synthetic method and Reimork.Tiemannf.synthetic method. PHBA is primarily used in pharmaceuticals, cosmetics and electronic industry. During 2005～2010, domestic demand of PHBA will be increasing by 11.4% annually.
