Description

  1. Product Overview

叔丁醇(TBA,又称特丁醇、2-甲基-2-丙醇)为无色结晶或液体,具有樟脑样特殊气味;熔点约 25.5 °C,因此在室温下可能呈固体或液体状态。与水完全混溶,亦溶于乙醇、乙醚等多数有机溶剂。

tert-Butanol (TBA, also tert-butyl alcohol / 2-methyl-2-propanol) is a colorless crystal or liquid with a characteristic camphor-like odor; melting point ~25.5 °C, so it may be solid or liquid at room temperature. Miscible with water and soluble in most organic solvents such as ethanol and ether.

本品是重要的化工中间体与溶剂,广泛用于 MTBE/ETBE 汽油添加剂合成、异丁烯制备、涂料与油漆溶剂、医药/农药/香料合成及实验室试剂等领域。

An important chemical intermediate and solvent, widely used in MTBE/ETBE gasoline-additive synthesis, isobutylene production, coating/paint solvents, pharma/agrochemical/fragrance synthesis and laboratory reagents.
