一般描述

甲醇(MeOH)是一种有机溶剂,具有广泛的工业应用。它是锂电池的主要成分。它可以在各种条件下通过CO2加氢制备。MeOH 是一种使乙醇变性的有毒醇。一项研究报告了在超临界条件下使用甲醇以菜籽油制备生物柴油。

应用

符合ACS规范。
High-purity, multipurpose solvent, tested for suitability in:
  • HPLC with gradient analysis
  • Spectrophotometry
  • Residual testing
  • LC-MS applications

Used as a solvent/reagent to determine total phenols content, anti-DPPH activity and the content of antioxidants in honeybee drone blood homogenate (DBH) samples.
