Abstract:
2-Perfluoroalkyl ethanols are obtained by reacting 2-perfluoroalkyl ethyliodides with at least the two-fold molar amount of nitric acid of about 70 to 98 percent strength and hydrogenating the intermediates, which are the nitrates of the desired ethanols. The products are useful as starting materials for the production of hydrophobic and oleophobic textile finishing agents, e.g. the polymer acrylates and methacrylates of said 2perfluoroalkyl-ethanols.
Abstract:
Halogenated esters of carboxylic acids are prepared by reacting a nontertiary olefinic hydrocarbon with a carboxylic acid salt, a cupric halide and palladium chloride in the presence of an anhydrous solvent.
Abstract:
PROCESS FOR THE PREPARATION OF STABLE PENTOLITE FROM CRUDE PENTAERYTHRITOL TETRANITRATE COMPRISING AGITATING IN WATER A MIXTURE OF MOLTEN TRINITROPOTOLUENE AND CRUDE PENTAERYTHRITOL TETRANITRATE AT A TEMPERATURE ABOVE THE MELTING POINT OF THE TRINITROTOLUENE AND BELOW THE MELTING POINT OF THE PENTAERYTHRITOL TETRANITRATE, WHILE MAINTAINING THE PH OF THE WATER IN THE RANGE FROM 7 TO ABOUT 10, FOLLOWED BY SEPARATING THE PENTOLITE FROM THE AQUEOUS PHASE.
