摘要:
An electrical connection line (L) for an electrical unit of a motor vehicle, which electrical connection line serves to electrically connect the unit to an electrical power source which is arranged in the motor vehicle and/or to another electrical unit. The connection line (L) is designed as a three-phase line with three insulated electrical conductors (1, 2, 3), of which each has an electrical individual sheath (5) which is in contact with its insulation means (4) and is closed all the way around. An electrical outer sheath (7) which surrounds the three sheathed conductors (1, 2, 3) and is closed all the way around is also provided and a coupling element which is equipped with electrical contacts which are insulated from one another is fitted at least to one end of the connection line (L) in a moisture-tight manner, and the electrical conductors (1, 2, 3), their individual sheaths (5) and the outer sheath (7) are electrically conductively connected to the contacts of the said coupling element.
摘要:
Dyes of the formula ##STR1## where the ring A may be benzofused and R.sup.1 -R.sup.6 have the meaning defined in the specification, with the proviso that at least one quaternizable or quaternary group is present in the molecule; use of said dyes for dyeing or printing polymeric material, and novel amides of J-acid.
摘要:
A process for preparing di- or triarylmethane dyes by oxidation of di- or triarylmethanes in the presence of a diluent and of an oxygen transfer catalyst that contains a complexed heavy metal ion comprises using as oxidizing agent hydrogen peroxide, a hydrogen peroxide donor compound, an organic hydroperoxide or a percarboxylic acid and as the oxygen transfer catalyst a member of the class of the porphyrins, tetraaza[14]annulenes, phthalocyanines or tetraazacyclotetradecanes.

The sulfonamides have the formula ##STR1## where R.sup.1 is C.sub.1 -C.sub.13 -lkyl, substituted or unsubstituted phenyl, C.sub.1 -C.sub.8 -alkanoyl or substituted or unsubstituted benzoyl, andR.sup.2 and R.sup.3 are each independently of one another substituted or unsubstituted C.sub.1 -C.sub.13 -alkyl, substituted or unsubstituted C.sub.5 -C.sub.7 -cycloalkyl or substituted or unsubstituted piperidinyt, or R.sup.2 may also be hydrogen.
摘要:
J-Acid urea of the formula ##STR1## is prepared by reacting 7-amino-4-hydroxynaphthalene-2-sulfonic acid (J-acid) with urea at from 100.degree. to 140.degree.
