    摘要: Expanded styrenic polymers contain 1 to 20% by weight of one or more aromatic polyphosphonate compounds corresponding to the following structure I: wherein a and b are each from 0 to 6, with a+b being from 2 to 6, each R is independently hydrogen, unsubstituted or inertly substituted alkyl having up to 6 carbon atoms, —NO2, —NR12, —C≡N, —OR1, —C(O)OR1, or —C(O)NR12 (wherein R1 is hydrocarbyl or hydrogen), each R2 is independently hydrogen, alkyl or inertly substituted alkyl, each R3 is a covalent bond or a divalent linking group, and each R4 is independently an alkyl, aryl, inertly substituted alkyl or inertly substituted aryl group. The aromatic polyphosphonate compounds are effective FR additives for the expanded polymers.

    摘要: Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the addition of at least two chlorine atoms to an alkane and/or alkene with a catalyst system comprising one or more nonmetallic iodides and/or lower than conventional levels of elemental iodine and at least one Lewis acid. The present processes make use of sulfuryl chloride, or chlorine gas, as a chlorinating agent.

    摘要: Processes for the production of chlorinated alkanes are provided. The present processes comprise reacting one or more mono- and/or dichloroalkanes to form tri-, tetra- and/or pentachloroalkanes, with high regioselectivity. In those embodiments wherein a dichloroalkane is desirably utilized, it may advantageously be a vicinal dichloroalkane. Further, only one catalyst is utilized. The present processes make use of sulfuryl chloride as a chlorinating agent, rather than a gaseous chlorinating agent such as chlorine gas. Finally, the process uses lower intensity process conditions than at least some conventional processes, and thus, operating costs are saved.

    摘要: Processes for the production of chlorinated propenes are provided. The present processes make use of 1,2-dichloropropane, a by-product in the production of chlorohydrin, as a low cost starting material, alone or in combination with 1,2,3-trichloropropane. The present processes can also generate anhydrous HCl as a byproduct that can be removed from the process and used as a feedstock for other processes, providing further time and cost savings. Finally, the processes are advantageously conducted in the liquid phase, thereby presenting additional savings as compared to conventional, gas phase processes.
