Abstract
Nitrophenyl ethers of substituted mercaptobenzothiazoles, including those in which hydrogen atoms of the benzo group substituted by methyl, ethyl, propyl, alkoxy, nitro, amino, halogen &c., may be obtained by reacting the sodium or potassium salt of mercaptobenzothiazoles in which, for example, the following substituents are present:--5<1>-nitro, 6<1>-amino, 5<1> - chlor, 4<1> - ethoxy, 5<1> - nitro - 6<1> - chlor, 6<1>-hydroxy, 4<1>-methyl, 4<1>-phenyl, with a nitrochlorbenzene in which the nitro group is either ortho or para to the chlorine. The Specification as open to inspection under Sect. 91 comprises also performing the above reactions with dinitrochlorbenzene. This subject-matter does not appear in the Specification as accepted.ALSO:Aldehyde amine reaction products are added to mono nitrophenyl ethers of mercaptobenzothiazoles to form mixed accelerators. The nitrophenyl ether may be that of a non-substituted or of a substituted mercaptobenzothiazole, the effect being more marked in the case of the latter compounds, which by themselves have little accelerating effect. The aldehyde amine reaction products include crotonylidene aniline, aldol aniline, ethylidene aniline, propylidene aniline, butyraldehydeaniline condensate, and their further aldehyde reaction products and the reaction products of such aldehydes as crotonaldehyde, acetaldehyde, butyraldehyde and such amines as toluidine, xylidine, hexylamine, butylamine and ethylamine. The nitrophenyl ethers of the substituted mercaptobenzothiazole include those in which the hydrogens of the benzo group are substituted by methyl, ethyl, propyl, alkoxy, nitro, amino, halogen &c., and may be obtained by reacting the sodium or potassium salt of mercaptobenzothiazoles in which, for example, the following substituents are present:-51 nitro; 61 amino; 51 chlor; 41 ethoxy; 51 nitro 61 chlor; 61 hydroxy; 41 methyl; 41 phenyl, with a nitrochlorbenzene in which the nitro group is either ortho or para to the chlorine. Examples are given showing the effect of specific mixed accelerators in vulcanization. The Specification as open to inspection under Sect. 91 comprises also the use of dinitro-phenyl ethers of mercaptobenzothiazoles in admixture with aldehyde-amine reaction products, and gave detailed examples showing their use in vulcanization. This subject-matter does not appear in the Specification as accepted.
