    摘要: New compounds of the general formula (I) ##SPC1##and salts thereof were prepared by reacting a compound of the general formula (II) ##SPC2##with a compound of the general formula (III) or (IV) ##EQU1## and optionally saturating the --C=N-- bond. In the above formulaeR.sup.1 and R.sup.2 are always the same and represent a C.sub.1-4 alkyl group,R.sup.3 stands for hydrogen,R.sup.4 and R.sup.5 each represent hydrogen or a straight-chained or branched C.sub.1-16 alkyl group optionally having an unsubstituted or substituted phenyl, furyl or naphthyl substituent, wherein said substituted aryl groups may contain up to 3 alkyl, C.sub.1-3 alkoxy, benzyloxy, nitro, amino, lower alkylamino, di-lower alkylamino, methylenedioxy, alkylmercapto, alkylsulfonyl or halogen substituents, orR.sup.4 and R.sup.5 may form together with the adjacent carbon atom a C.sub.3-12 cycloalkyl or C.sub.3-12 cycloalkylidene group, one of the methylene ring members of which being optionally replaced by an imino, lower alkylimino, or phenyl-lower alkylimino group, andR.sup.6 and R.sup.7 may stand for hydrogen, or R.sup.6 and R.sup.7 may form together a valence bond, andThe R.sup.8 groups may each represent hydrogen, lower alkyl or alkanoyl, or the two R.sup.8 groups may form together a lower alkylene or alkanoylene group.The compounds of the general formula (I) possess primarily gastric acid secretion inhibiting and central nervous activities, furthermore they exert favourable action on the development of certain microorganisms which can be utilized in therapy.

    摘要: The invention is a process for monitored cross-linking of unsaturated polyester resins in the presence of a metal-ion-containing accelerator and an organic peroxide initiator, complemented by promotor in some cases. According to this process, the cross-linking is carried out in the presence of one of the compounds from the group consisting of alizarin, sodium alizarinesulfonate, 3-nitroalizarin, chinizarine, or purpurin, where the substituents are H atoms or OH, NO.sub.2, SO.sub.3 H, or SO.sub.3 Na groups with the restriction that at least one of them should be other than H, which is present in a ratio of from 0.005 to 0.5, preferably 0.01 to 0.1 percent (mass/mass), compared to the mass of the polyester resin, and cross-linking is trailed by the color change in the system. The invention permits all of the chemical-technological processes involved in the processing of unsaturated polyester resins to be monitored visually.
