Title: A process for the production of a cationic surface-active additive for bitumen together with piperazine and ethylenediamine
Inventor: BOLGAR LESLIE
IPC: C07D295/023
Filed: 1955-04-07
Abstract: Piperazine and ethylene diamine, along with a cationic surface-active additive for bitumen, are produced when one or more of the amine compounds having the formula NH2-CH2CH2-NH-CH2CH2-R, in which R is -OH, -NH2, -NHCH2CH2NH2 or a higher polyethylene polyamino radical, are acidified by at least one halogen acid and heated at 150-300 DEG C. for at least 2 hours; the gaseous distillation products from the reaction mixture are cooled and the resulting condensate separated to yield ethylene diamine and piperazine; the residual heat-condensation product from the distillation is partly amidified with one or more fatty acids to give a surface-active additive for bitumen.  In an example, diethylene triamine is mixed with ammonium chloride and the mixture is heated to 240-260 DEG  C.; ammonia is evolved and a distillate which yields ethylene diamine, piperazine and diethylene triamine is obtained; the diethylene triamine is recycled; the residual heat-condensation polyamine product is treated with caustic soda and the free polyamines so formed are partly amidified by heating with oleic acid to give a surface-active additive for bitumen having the formula C17H33CONHRNH2 in which R is -CH2.CH2- or a longer chain.

The preferred mixture lies in the range between BaO.Al 2 O 3 .0À48 Ba and 0À34 BaO. Al 2 O 3 . 0À89 Ba. Such an emissive material may be made by mixing the requisite amount of aluminium powder having a grain size of 3Á with a barium aluminate compound which may contain excess BaO, for example 1À76 BaO. Al 2 O 3 . The mixture may then be coated on a cathode body such as a nickel grid, an iron cup or a tungsten coil by dipping the body into the dry powder, or into a slurry of the mixture with butylacetate or by inserting particles or pellets of the pressed mixture into the cathode. The cathode is activated by heating to a temperature between 600‹C. nd 1200‹C., preferably to 660‹C. at which temperature the aluminium reacts with some of the barium oxide to form Ba and Al 2 O 3 , no gases being evolved. The activation may be carried out by the usual methods such as heating by radiation, passing current through the cathode coil, low pressure arc or glow discharge in argon or by conduction from a hot surface, in particular by heat conducted from a source used to seal the cathode in a glass tube. The activation may also take place in an atmosphere of hydrogen or an inert gas or in a vacuum.
