A mixture of phenylisopropylmethyla

A mixture of phenylisopropylmethylamine 150, d-tartaric acid 82.5, and H2O 330 g was treated with HCl to pH 4 to deposit 120 g L-phenylisopropylmethylamine-d-tartrate salt, which gave 88 g L-phenylisopropylmethylamine. The D-enantiomer (58 g as the HCl salt) was isolated from the filtrate(过滤).

結果 (中文) 1:

Phenylisopropylmethylamine 150、 d-酒石酸 82.5 和 H2O 330 g 的混合物与盐酸受到 pH 4 存 120 g L-phenylisopropylmethylamine-d-酒石酸盐，给了 88 g L phenylisopropylmethylamine。D-对映异构体 (58 g 作为盐酸盐) 是从 filtrate(过滤) 中分离。
