For 2,2-dichloropropane and 1,1-dichloropropane elimination of HCl occurs but for 1,1-dichlorobutane, -pentane and -hexane partial hydrolysis followed by elimination of HCl gives E, E-, E,Z- and Z,Z- isomers of the dialk-1-enyl ethers and fully assigned 13C NMR data are presented ...
As a contribution to solving this problem, the present invention proposes to replace the compositions based on F113 by a novel composition based on methyl tert-butyl ether (thereafter MTBE) and 1,1,1,2,2-pentafluoro-3,3-dichloropropane. The latter compound, known in the art under the name...
Enzymes and microorganisms were screened for the enantioselective hydrolysis of (±)-1-acetoxy-2,3-dichloropropane (1) which is convertible to epichlorohydrin. Pancreatin and steapsin from hog pancreas were found to hydrolyze (±)-1 asymmetrically to give (S)-1 of 90% enantiomeric excess (e.e...
The addition of water under mild acidic conditions gives 3-hydroxypropionaldehyde with high selectivity. Preferentially buffer solutions with a pH 4-5 or weak acidic ion exchange resins are used as catalysts. Further hydrogenation of this aqueous solutions gives 1,3-propanediol. There is an alternati...
