Title: Preparation of orthophenylphenol
Inventor: JIYOU YASUYA
IPC: C07C37/01
Filed: 1979-07-27
Abstract: PURPOSE: To prepare orthophenylphenol in high yield without using severe conditions, by reacting dibenzofuran with sodium hydride in an inert organic solvent having a boiling point limited in a specific range at a temperature within a specific range under pressure in an inert gas atmosphere.  
     CONSTITUTION: Orthophenylphenol is prepared by reacting dibenzofuran with sodium hydride in an inert organic solvent having a boiling point of 140W300°C, at 200W300°C under pressure in an inert gas atmosphere. The organic solvent is, e.g. tetrahydronaphthalene, decahydronaphthalene, cyclohexylbenzene, methylnaphthalene, etc. As an alternative method, the desired compound may be prepared by reacting sodium metal with hydrogen in the solvent to give sodium hydride and reacting the product with dibenzofuran without separation of the product. The yield of the desired compound is increased by pressurizing the reaction system to ≥3kg/ cm 2  during the introduction of hydrogen gas.

Filed: 1979-07-27
Abstract: PURPOSE:To make it possible to observe accurately the emulsion particles of rolling oil by slowing down the flow of a sample by operating and stopping a sampling pump provided to the bypass of a liquid supply pipe for the rolling oil. CONSTITUTION:From rolling-oil supply pipe 1, a sample is sucked to sampling pump Ps by way of reverse washing system B and then the sample is returned to pipe 1 by way of return flow pipe 3 and liquid sampling pipe 5. Liquid sampling pipe 5 is provided with cell C for observation and pipe 5 is so arranged that its terminal opening part 6 will face to the upstream. Removal system D for iron powder, etc., is provided. As pump Ps is stopped, reverse flow is generated from opening part 6 to pipe 3. Because of forward flow with pump Ps in operation and the reverse flow, no particle is deposited or sticking in the flow passage of cell C and the flow is slowed down. In this state, photographing or microscope observation with cell C makes it possible to observe accurately the action of emulsion particles.
