The diastereoisomeric quinine salts of (±)-β-(1-trifluoromethylethoxy)propionic acid, deposited from aqueous solvents as monohydrates, were separated by crystallisation to yield, by methods already described,1(–)-1-tri-fluoromethylethanol, [α]D25–5·65°.
从水溶剂中以一水合物形式沉积的(±)-β-(1-三氟甲基乙氧基)丙酸的非对映异构体奎宁盐,通过结晶进行分离,从而通过已描述的方法得到1(–)-1-三氟甲基乙醇,[ α] D 25 –5·65°。
