Washington Post, June 1, 2007. 17. J. A. Hunt, A short history of soap, Pharm. , 1999, 263, 985. 18. 6 million to $82 million. DuPont used these profits to diversify its business into dyestuffs, plastics, and paints. 19. The US agribusiness Archer Daniels Midland recently announced plans to make propylene glycol from glycerol instead of propylene oxide, in a process that employs advanced catalysts. Dow Chemical closed its glycerol plant in Texas early in 2007 when Procter & Gamble Chemicals shut down a natural glycerol refinery in England.

Reproduced from ref. 43, with permission). Furthermore the researchers established a quantitative relationship between solvent polarity and rate of epoxidation, leading to the conclusion that the best solvents for this transformation should have good hydrogen bond donor capability, but low hydrogen bond acceptance (Lewis basicity). The robustness of the regression model has been tested and can successfully predict the behavior of new glycerol-derived solvents in this epoxidation reaction. Finally, the solvents employed under oxidation conditions showed remarkable stability, even in the case of secondary alcohols.

24 The process runs at higher temperature and pressure than the homogeneous method, and uses an excess of methanol, which is vaporized and recycled. 12). 12 Simplified schematic of the IFP Esterfif biodiesel process, based on two consecutive reactor–separator stages (reproduced from Ref. 24, with permission). 27 This intensifies mass transfer, allows in situ energy integration, reduces equipment costs, and simplifies the process flow sheet and operation. 28 For example, thanks to novel catalyst and integrated process design, the heterogeneous process saves up to 40% of capital costs and 30% of operating costs compared to a conventional plant.
