Abstract: The invention relates to complex compounds of rhodium, iridium or ruthenium with a silicic acid-like structure with a least one phosphine ligand, the trivalent phosphorus of which is bonded to silicon via at least one divalent organic residue, the remaining three valences of the silicon building, via oxygen bridges arising from the hydrolysis of functional substituents originally bound there, a inter- or intra-molecularly crosslinked polycondensate. The required charge equalization is effected by an anion. Also disclosed are processes for recovery of the polymeric complexes and their use in heterogeneous catalysis of various chemical reactions.

Abstract: Prezenta inventie se refera la un procedeu pentru obtinerea acidului cianhidric dupa asa numitul procedeu BMA, procedeu ce consta în insuflarea, totala sau partiala, a amestecului de gaze format din amoniac si hidrocarburi alifatice cu catena scurta, de preferinta metan, printr-un tub de introducere prevazut cu unul sau mai multe orificii, dispus în tubul de reactie, la o presiune preliminare de cel putin 1,2 bar, amestecul gazos fiind lasat sa curga cu o viteza de peste circa 200m/s din orificiile tubului, dupa care gazele produse sunt prelucrate în mod obisnuit. Drept hidrocarburi ce pot fi luate în consideratie, în afara de metan, ca hidrocarburi alifatice cu 3 si 4 atomi de carbon, sunt gazele lichefiate propan, n-butan si i-butan, la utilizarea acestor gaze lichefiate trebuind sa fie prezent si hidrogenul, si anume, într-un raport atomic C:N:H de 1:1:7,1 pîna la 1:1,33:12. în prezent, la scara industriala se utilizeaza, în special, metan, care se foloseste atît în stare pura, cît si sub forma obisnuita, de exemplu ca gaz de pamînt sau gaz de rafinarie. în cazul utilizarii gazului de pamînt si a gazului de rafinarie, se prefera gazele cu un continut total de metan de 60 pîna aproape de 100% în volume, care contin doar mici cantitati de hidrocarburi superioare...

Abstract: Bis-(silyl-ethyl)-oligosulphide obtained by reacting a vinyl silane having the formula (CH2=CH)m-SiR?R4-(m+n) wherein R represents chlorine, iodine, C1-C3-alkoxy, 2-methoxy-ethoxy, 2-ethoxy-ethoxy or hydroxy, R1 represents C1-C3-alkyl, phenyl or C5-C7-cycloalkyl, n is 0, 1 or 2, m is 1 or 2 and m + n is 1, 2 or 3, with sulphur and, when required, with hydrogen sulphide in a molar ratio ranging from 1:2.5 to 1:10 and of vinyl silane to hydrogen sulphide from 1:0 to 0:5 at a temperature between approximately 100 and 200.degree.C under a pressure ranging from 1 to 25 bars (total pressure at the reaction temperature) and in the presence of Sulphidation catalysts and when required hydrolysis or partial hydrolysis of the reaction product. The corresponding process of production and the use of a bis-(silyl-ethyl)-oligosulphide as a reinforcing additive (adhesion promoter) in a crosslinkable rubber mixture containing a silicate filler and when required carbon black as well as sulphur and other conventional mixture components are also disclosed.

Abstract: In order to be independent of the situation in regard to methane and natural gas and at the same time to obtain a heating gas there is employed in the hydrocyanic acid-methane-ammonia process (the BMA process) in place of methane an alkanol or alkanediol having 2-4 carbon atoms, preferably ethyl alcohol, and this is reacted with ammonia in a C:N ratio of 0.8:1 to 2:1. Optionally additional hydrogen can be present.

Abstract: Element, preferably in panel form, for use as thermal insulation, comprising …… a) a finely dispersed, pulverulant or fibrous substance, … b) a microporous covering and … c) a gas-tight and water-proof metal-free covering. …… The element is produced by drying the pulverulant or fibrous substance, if appropriate, introducing it into a microporous covering, if appropriate, compressing it, if appropriate, and then drying it, if appropriate. After that, the pulverulant substance with the microporous covering is introduced into a gas-tight and water-proof, metal-free covering. If appropriate, this gas-tight and water-proof covering is evacuated and sealed. … …
