Compositions thermoplastiques ignifuges de polystyrène et de polyoléfine, thermostables et inaltérables à la lumière, comprenant un (des) composé(s) bicycliques de phosphate, un (des) ignifuge(s)contenant de l'halogène et des résines de polystyrène ou de polyoléfine. Ces compositions ont moins tendance à prendre des couleurs, à changer de viscosité de fusion ou à perdre leur résistance mécanique lorsqu'elles sont soumises au traitement du polymère et à l'utilisation finale.
摘要:
A process for the production of an aldehyde by hydroformylation of an olefin comprises: providing a hydroformylation zone containing a charge of a liquid reaction medium having dissolved therein (a) a complex rhodium hydroformylation catalyst comprising rhodium in complex combination with carbon monoxide and with a cyclic phosphite having a bridgehead phosphorus atom linked to three oxygen atoms at leasttwo of which form together with the bridgehead phosphorus atom part of a ring and (b) a ligand stabilising amount of a tertiary amine; supplying said olefin to the hydroformylation zone; maintaining temperature and pressure conditions in the hydroformylation zone conducive to hydroformylation of the olefin; supplying make-up hydrogen and carbon monoxide to the hydroformylation zone; and recovering from the liquid hydroformylation medium a hydroformylation product comprising at least one aldehyde.

摘要:
The invention relates to a galvanic cell having a lithium metal or an alloy comprising a lithium metal as anode material, having an electrolyte comprising lithium bis(oxalato)borate and at least one other lithium complex salt of the formulae (I) and/or (II) in an aprotic solvent or solvent mixture, wherein the ratio of the compound (I) and/or (II) in the conducting salt equals 0.01 to 20 mol % and X, Y and Z in the formulae (I, II) is a bridge having two oxygen atoms bonded to the boron or phosphor atom, selected from (Formula (III)) wherein (i) Y 1 and Y 2 together = O, n = 0 and Y 3 and Y 4 are independently of one another H or an alkyl remnant having 1 to 5 C atoms, or (ii) Y 1 , Y 2 , Y 3 , Y 4 independently of one another are each OR (R= alkyl remnant having 1 to 5 C atoms), H or an alkyl remnant R 1 , R 2 having 1 to 5 C atoms, and wherein n = 0 or 1.
摘要:
A bis(pentaerythritol phosphate alcohol) alkylphosphonate compound, such as one comprising an alkyl group of from about one to four carbon atoms, preferably bis(pentaerythritol phosphate alcohol) methylphosphonate, is a flame retardant compound. Such a compound can be prepared by the transesterification of a diphenyl alkyl phosphonate carrying the desired alkyl group with pentaerythritol phosphate alcohol. An alternative process of preparation comprises the reaction of pentaerythritol phosphate alcohol, a trialkylamine, and an alkylphosphonic dihalide.
