melting point apparatus

A New YB_1 Drug Melting Point Measurement Apparatus

YB-1型药物熔点仪的研制

Firstly, a new functional monomer 5-chloro-sulfonyl isophthalic chloride ( CSIC) was prepared. The chemical structure of the monomer was proved by infrared spectroscopy ( IR) while the melt point and purity were determined by melting point apparatus and liquid chromatograph.

首先制备了功能单体5-氯磺酰异酞酰氯（CSIC），其结构由红外光谱（FT-IR）验证确定，熔点仪及液相色谱仪分别测定其熔点和纯度。

days #2 & 3: recrystallization. calibration of the melting point apparatus.

第#2和第3天：再结晶…熔点仪的校正。

The apparatus is calibrated using appropriate substances of known melting point.

装置使用一个已知熔点的合适物质去校准.

Used melting point determination apparatus, infrared spectroscopy, nuclear magnetic resonance spectroscopy and GC determination on product characterization.

采用熔点测定仪、红外光谱、核磁共振以及气相色谱对产物进行分析表征。
