Abstract: An improved system for performing an alkylation process and a method for handling liquid catalyst in an alkylation process. This improvement involves method and apparatus by which liquid alkylation catalyst contained in the alkylation process equipment can be transferred into a catalyst storage vessel without the need for venting excess pressure from the storage vessel to atmosphere. Through a combination of the physical arrangement of the process equipment and the storage vessel along with the addition of a pressure equalization line, apparatus is provided whereby certain process steps can be followed which allow the transfer of catalyst from the process equipment to the storage vessel without venting the storage vessel. The improvement comprises physically locating the catalyst storage vessel at a relative elevation below the alkylation proces equipment and providing a line to connect the vapor space of the storage vessel with that of a catalyst settling vessel in the process equipment.

Abstract: A process for the preparation of metal fluorides usable for the production of fluoride glasses consists of reacting in an organic liquid medium, such as toluene, (a) a compound of said metal chosen from among the gaseous compounds thereof, the compounds of said metal soluble in the organic liquid medium and the compounds of said metal in solution in an organic solvent miscible with said medium, and (b) a fluorinating agent chosen from among the gaseous fluorinating agents, the fluorinating agents which are partly soluble in the organic medium and the fluorinating agents which are partly soluble in an organic solvent miscible with said medium, to form a fluoride of said metal, the organic liquid medium being such that it reacts neither with the compound of the metal, nor with the fluorinating agent and does not dissolve the fluoride formed. To prepare the zirconium tetrafluoride, it is possible to introduce in toluene, gaseous Zr(BH.sub.4).sub.4 entrained by argon from the container and HF vapor also entrained by the argon from the other container. ZrF.sub.4 precipitates in the toluene and is separated on the filter.
