Abstract

Terpineol, a promising valorisation product of pine industry, is widely used as an active ingredient for disinfectant soap, cleansers, perfumes, and pharmaceutical purposes. Synthesis of terpineol is generally carried out by separation of α-pinene compounds from crude turpentine through fractionation and then hydrated (addition of water) with the help of acid catalysts. However, direct turpentine hydration without pre-fractionation process can be more beneficial from economic and process point of views. This study aims to investigate the effect of both single and mixed/combined catalysts towards terpineol yield. Combined strong and weak acid catalysts were required to obtain high feed conversion and terpineol yield. The selectivity of terpineol is then correlated to the solubility of a weak/organic acid. In this study, the highest yield of terpineol was 54.0 ± 8.2%-w/w using combination of formic acid and sulphuric acid.

摘要

松油醇是松脂工业中一种很有前景的增值产品，被广泛用作消毒皂、清洁剂、香水及医药用途的活性成分。松油醇的合成通常是先通过分馏从粗松节油中分离出α-蒎烯化合物，然后在酸催化剂的作用下进行水合（加水）反应。然而，从经济和工艺角度来看，不经过预分馏过程直接对松节油进行水合反应可能更具优势。本研究旨在探究单一催化剂以及混合/组合催化剂对松油醇产率的影响。需要使用强酸和弱酸组合催化剂才能实现高原料转化率和松油醇产率。松油醇的选择性随后与弱酸/有机酸的溶解度相关。在本研究中，使用甲酸和硫酸的组合时，松油醇的最高产率为54.0±8.2%（重量/重量）。
