薄荷脑(Menthouml)又名薄荷冰,商品呈无色透明的棱柱状结晶;冰片(Borneolum Syntheticum)又名合成龙脑,商品呈无色透明或白色半透明的片状结晶.二者形态完整时不难鉴别,但研细后均为白色粉末,均有强烈辛凉香气,颇难区分.山西省某单位制仁丹时曾将两种粉末混淆,造成投料失误.现介绍一种简易、快速的鉴别方法,供参考. 取完整的薄荷脑少许,研成细末(下称“甲样品”).再取待鉴定粉末少许(下称“乙样品”),将二者混合研磨半分钟,若仍呈固体状态,则可断定
Menthouml, also known as mint ice, is colorless and transparent prismatic crystals; Borneolum Syntheticum is also known as synthetic borneol, and the product is colorless, transparent or white translucent flaky crystals. It is not difficult to identify, but after the research is fine, white powder, all have a strong pungent aroma, quite difficult to distinguish. A unit in Shanxi Province, Ren Dan used to confuse the two powders, resulting in mistakes in feeding. Here is a brief and quick introduction. Identification method for reference. Take a complete menthol a little research into fine (hereinafter referred to as “A sample”). Then take a little powder to be identified (hereinafter referred to as “B sample”), the two were mixed and ground for half a minute, if Still in solid state, it can be concluded
