Description

General description: 1,2-Propanediol, a 1,2-alkanediol[1] is an industrially important chemical. Due to its increasing demand many green methods have been proposed for its synthesis mainly using the inexpensive glycerol as the starting material.[1][2][3][4][5][6] It is a raw material for the synthesis of intermediates, building blocks and polymers.[7]
Application: 1,2-Propanediol may be used in the following processes:Green synthesis of propylene carbonate.[8]Production of lactic acid by green catalytic oxidation.[9][10]Propanal generation by catalytic dehydration.[11]
Other Notes: The article number 398039-4X2L will be discontinued. Please order the single bottle 398039-2L which is physically identical with the same exact specifications.
