Major Traditional Methanol Derivatives

The major traditional derivatives for methanol are described here. 

The carbonylation of methanol to produce acetic acid was developed in the 1970s by Monsanto, and BP Chemieals has now taken over this process and development. It is the most efficient route to acetic acid, and because of this it

This protocol focuses on the analysis of chlorophyll a and b, and the more nonpolar derivatives, including pheophytins and pyropheophytins. An octadecyl-bonded, reversed-phase stationary phase is used with a methanol/water mixture and ethyl acetate mobile phases in a gradient elution to provide rapid and complete separation of the major chlorophyll derivatives in 25 to 30 min. This is coupled with traditional UV/visible spectrophotometric detection at 654 nm to selectively screen these photosynthetic pigments in food and plant tissues.
