| titleOfInvention | Process for the manufacture of condensation products of ª‡-ª‰-substituted acroleins with aromatic bases |
| abstract | 323,512. I. G. Farbenindustrie Akt.- Ges., and Kropp, W. Oct. 3, 1928. Addition to 264,674. Aldehyde-amine condensation products. - In the process for the manufacture of condensation products from alpha-#-substituted acroleins and aromatic amines described in the parent Specification, organic or inorganic acids are used as condensing agents. The products, with or without purification, may be used as vulcanization accelerators, especially in admixture with lamp black, and in general surpass those of the parent Specification, the use of which, in vulcanizing indiarubber, is claimed in Specification 264,673, [Class 70, Indiarubber &c.], as condensing agents, fatty acids are preferred, especially those containing from 1-18 corbon atoms, such as formic, acetic, propionic, butyric and stearic acids, but other acids, organic or inorganic, may be used, hydrochlorine, salicylic, cinnamic, oxalic, and succinic acids, and aromatic sulphonic acids being specified. Instead of the aldehydes themselves, substances adapted to yield them during the reaction may be employed, such as oximes or the corresponding aldols. Organic solvents, such as benzene or toluene, may also be used. In examples (1) alpha-ethyl-#-propylacrolein is condensed with aniline in the presence of glacial acetic, n-butyric, or stearic acids, under various conditions, in the presence or absence of benzene; in some cases the crude alpha-ethyl-#-propylacrolein obtained from n-butyraldehyde and caustic soda is employed as parent material, (2) alpha-ethyl-#-propylacrolein is condensed with m- or p-toluidine or alpha-naphthylamine in the presence of glacial acetic acid, and (3) alpha-n-amyl-#-phenylacrolein (Specification 284,458) is condensed with aniline in the presence of glacial acetic acid. Other alpha-#-substituted acroleins, such as alpha-methyl- #-ethylacrolein, and alpha-isopropyl-#-isobutylacrolein may also be used. |
