摘要

特用化學品（specialty chemicals）是指規模小、種類多、用途特殊多元、技術需求度高、附加價值高的化學品。其所涵蓋的範圍很廣，為工業、農業、民生、國防、科技等眾多產業之基礎，也是台灣化學產業適合轉型的方向。在環安與永續發展的前提以及新興科技的崛起，低毒性環保材料、高性能高分子以及複合材料將是產業未來發展趨勢。觸媒氫化製程具有高產率、低廢棄物的特色，為綠色製程技術，也是由傳統大宗化學品轉型為高值特用化學品發展的重要製程技術。工研院近期開發一系列氫化觸媒專利技術，具有於低氫氣壓下達到高轉化率與高選擇性的特色，可用於氫化型鄰苯二甲酸酯可塑劑、氫化雙酚A等高安全性材料，也可用於1,4-環己烷二甲醇及2,2,4,4-四甲基-1,3-環丁烷二醇等高性能聚酯材料中間體的合成，以及高強度耐候複材樹酯硬化劑－二胺基二環己基甲烷系列脂環胺的合成。本文將氫化技術運用於上述低毒性環保材料、高階聚酯材料中間單體，以及複材樹酯硬化劑的生產做一說明。

Specialty chemicals demonstrate wide varieties in kinds and functions. They are usually produced in low volume but with high-demand of technologies, which makes them high value added. Specialty chemicals are applied broadly and fundamental of various sectors, including manufacturing, agricultural, civilian, military, and novel-tech industries. It is necessary for the chemical industries in Taiwan to transform the commodity to the specialty chemicals in order to retain the international competitiveness. With the raising sense of environmental protection and sustainability as well as the need for the emerging technologies, low-toxic, high performance chemicals, polymers, and composite materials are the trend for the future development in chemical industry. Catalytic hydrogenation is considered as a green process, which usually exhibits high product yield, and low waste production. Due the versatility of hydrogenation, it is the crucial process for specialty chemicals production. Industrial Technology Research Institute (ITRI) developed a series of patented heterogenous hydrogenation catalysts and technologies, which exhibits high activity and selectivity under relatively low hydrogen pressure. The catalysts have been demonstrated in the production of high ecofriendly chemicals such as 1,2-cyclohexane polycarboxylic acid esters, hydrogenated bisphenol A, and key intermediates for polyester, 1,4- cyclohexandimethanol, 2,2,4,4-tetra-methyl-1,3-cyclo-butanediol. In addition, the alicyclic diamines type curing agents used for high strength, weatherability, and light-weighted composite materials, diaminodiphenyl methane could also be produced by the abovementioned catalytic hydrogenation. This article provides the induction and discussion on applications of the hydrogenation processes or the production of low-toxic chemicals, key intermediates for the high-end polyester, and curing agents for the robust composite materials.
