OHORODNIK, ALEXANDER, DIPL.-CHEM. DR.HAUSER, ALFRED, DIPL.-CHEM. DR.DE2423079A1 * May 13, 1974 Nov 27, 1975 Hoechst Ag Purifying acetic acid contg. acetic anhydride - by adding super-stoichiometric water quantity and distilling with dissolved alkali(ne earth) acetate...
Acetic anhydride was gradually being titrated into a mixture of chromic anhydride and acetic acid in a 20-gallon, glass-lined tank. After 1 1/2 hours of this procedure, the contents of the reactor exploded.Mixing glacial acetic acid and oleum in a closed container caused the temperature and ...
(see the section on spacer arms, this chapter). The final coupling of the iodoacetate molecule onto the amino spacer can be performed using iodoacetic anhydride or NHS-iodoacetate, or through a carbodiimide (EDC) coupling procedure to attach the carboxylate to the amine through an amide bond....
6,127,432 describes processes for the conversion of a feedstock comprising carbon monoxide and hydrogen to a product stream comprising at least one of an ester, acid, acid anhydride and mixtures thereof. U.S. Pat. No. 6,127,432 also describes a process for converting an alcohol, ether and...
The hydrolysis of acetic anhydride to acetic acid in water as solvent was monitored by Raman microscopy. Both static and flow-through configurations were used in the experiments, and various experimental designs, i.e., multiple-experimental runs and multiple-perturbation semibatch mode, were considere...
