Abstract: Inventia se refera la un procedeu de obtinere a acidului cianhidric din metan si amoniac, constînd în aceea ca, în scopul recuperarii amoniacului din gazele obtinute de la zona de sinteza care contin acid cianhidric, hidrogen, metan nereactionat, amoniac, mici cantitati de azot, oxid de carbon si eventual apa, gazele de reactie se aduc în contact cu zeoliti de tip structural A, I, F, P, respectiv zeoliti naturali alesi din grupa constituita din mordenit, clinoptinolit sau crionit.

Abstract: The known hydrocyanic acid-methane-ammonia (BMA) process for the production of hydrogen cyanide can now be carried out with liquified gases namely through the presence of additional hydrogen at the beginning of the reaction. The atomic ratio of carbon to nitrogen and hydrogen is from 1:1:7.1 to 1:1.33:13. As additional hydrogen there is the portion of hydrogen present coming out of the reaction "hydrocarbon+NH3". Otherwise the reaction conditions are the same as in the known BMA process.

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: 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. … …

Abstract: The present invention relates to organosiloxaneamine copolycondensates as statistical or block copolycondensates or mixtures thereof of groups (I) and ( II) R1 to R6 is (III) and R6 is bonded directly to the nitrogen atom or to the two linked radical X and is an alkylene group, a cycloalkylene group or oder wherein n is 1 to 6 and m is 0 to 6. The free valences of the oxygen atoms that are bound to the silicon atom are saturated by silicon atoms of further groups of formula (III) optionally with the incorporation of cross-linking agents. X stands for ?N-H, ?N-CH3, ?N-C2H5, -S-, -S2-, -S3-, -S4-, ' ' wherein R" is H or an alkyl group. In addition, production methods and the use of the product for the removal of dissolved metals from a liquid phase or for the absorption of gaseous compounds are described.

Abstract: A process for the dismutation of chlorosilanes is proposed. In this process chlorosilanes are passed over a catalyst that is either unmoulded or in the form of pellets and consists of four different organopolysiloxane compounds carrying substantially an amino or ammonium grouping as functional group and is crosslinked when required, the chlorosilanes being passed over the catalyst either in the form of a gas during 0.01 to 100 seconds at 55 to 100.degree.C or as a liquid during 1 to 1000 seconds at 25 to 55.degree.C.
