摘要： A method of dehalogeno-dimerizing an aromatic halide compound substituted by at least one halogen atom substituted on the aromatic ring using a palladium catalyst on support in the presence of water, a reducing agent and a halogen acceptor is disclosed. The method is characterized by using the palladium catalyst on support immersed in a hydrohalogenic acid prior to the dehalogeno-dimerization reaction.

摘要： Apparatus for producing a polishing solution composed of pure water and abrasive grains, the apparatus including a preparation tank to prepare a polishing solution containing abrasive grains at a predetermined concentration, by mixing an abrasive grain-containing slurry and pure water, and a circulation device for circulating the thus prepared polishing solution to keep the solution in a suspended state. The circulation device includes a circulation conduit and a flow-controllable bypass conduit fluidly associated with the circulation conduit providing a constant flow rate and having a light-extinction type particle detector for monitoring the polishing solution so as to detect large abrasive grains having a particle size not less than a predetermined value and measure the number of the large abrasive grains.

摘要： A method of separating a liquid mixture wherein the liquid mixture is heated; the heated liquid mixture is supplied to a pervaporation membrane module to separate a permeable component of the liquid; a portion of non-permeated liquid is circulated through a circulation pipe into a liquid mixture feeding pipe before a heater, and the remaining portion of the non-permeated liquid is extracted to the outside of the system, and wherein the temperature of the liquid in the liquid mixture feeding pipe in which the non-permeated liquid has been mixed with the liquid mixture or in the circulation pipe for the non-permeated liquid, is measured, and when the measured temperature is out of a predetermined range, new supply of the liquid mixture and/or extraction of the non-permeated liquid is stopped.
