摘要:
A process for maintaining a property P of a polyisobutene around a target value V during a continuous polymerisation of isobutene in a reactor containing a boiling liquid reaction phase in equilibrium with a gas phase above the liquid phase. The process comprises continuously introducing, into the reactor, a catalyst and a C4 hydrocarbon feed and continuously withdrawing, from the reactor, the liquid reaction phase which is subsequently subjected, continuously, to at least one purification step to isolate the polyisobutene. The property P is chosen amongst the viscosity and the average molecular mass of the polyisobutene. The property P is maintained around the target value V (i) by measuring the isobutene partial pressure (PiC4) in the gas phase of the reactor, (ii) by calculating the isobutene concentration (CiC4R2) in the boiling liquid reaction phase by means of a first model predicting the value of CiC4R2 from the measured value of PiC4 and being based on liquid/vapor equilibrium law, (iii) by calculating an instantaneous value Pinst of the property P by means of a second model predicting the value of Pinst from the calculated value of CiC4R2 and including at least one function of the isobutene polymerisation kinetics, and (iv) by varying at least one process parameter so as to make the instantaneous value Pinst tend towards the target value V.

摘要:
A process is disclosed for the preparation of zinc alkyl chain growth products via a catalysed chain growth reaction of an alpha-olefin on a zinc alkyl, wherein the chain growth catalyst system employs a group 3-10 transition metal, or a group 3 main group metal, or a lanthanide or actinide complex, and optionally a suitable activator. The products can be further converted into alpha-olefins by olefin displacement of the grown alkyls as alpha-olefins from the zinc alkyl chain growth product, or into primary alcohols, by oxidation of the resulting zinc alkyl chain growth product to form alkoxide compounds, followed by hydrolysis of the alkoxides.
