Title: Production of biphenols
Inventor: KITAMURA TAKU
IPC: C07B61/00
Filed: 1989-01-23
Abstract: PURPOSE:To suppress side reaction and produce biphenols in good yield by oxidatively dimerizing phenols in a molten state using a strong basic alkali metal compound as a catalyst. CONSTITUTION:Phenols, such as 2,4- or 2,6-dialkylphenol, are oxidatively dimerized in a molten state under substantial anhydrous and solventless conditions using a strong basic alkali metal compound as a catalyst to afford biphenols (e.g. 3,3',5,5',-tetra-tert-butyl-4,4-dihydroxydiphenyl). An alkali metal hydroxide, oxide, alkoxide or phenoxide is preferred as the strong basic alkali metal compound. An oxygen-containing gas is preferably introduced in the presence of the catalyst to carry out oxidative dimerization and part or all of the catalyst is then neutralized to simultaneously stop the introduction of the O2-containing gas. Protonic disproportionation reaction is preferably carried out above a temperature of the oxidative dimerization. Thereby, the yield per batch is high and the method is effective.

Title: Surface bonding device
Inventor: SAKAI EIJI
IPC: B29C65/48
Filed: 1990-01-24
Abstract: PURPOSE:To prevent a bonding agent layer from getting mixed with foams by providing upper and lower tables for fixing first and second materials to be bonded and a turnover driving mechanism and turning over the upper table after applying a bonding agent and an up and down driving mechanism for pressure bonding the bonding surfaces of the first and second materials to be bonded on the upper surface section. CONSTITUTION:First and second materials 1 and 2 to be bonded are fixed on the upper surface sections of upper and lower tables 4 and 5 and a bonding agent 3 is applied linearly on a bonding surface 1a of the first material to be bonded 1 while a coating head 7 of a bonding agent applying device 21 is moved. A turnover driving mechanism 22 is actuated and the upper table 4 is turned over in a manner of facing the bonded surface 1a of the first material to be bonded 1 downward. Even in the case that the applied bonding agent 3 is of low viscosity by turn the bonding surface 1a downward, the bonding agent 3 is prevented to be stretched all over and flattened, and the swelling downward is enlarged by gravity. Thus, the bonding agent area to be brought into contact first at the time of overlapping the first and second materials 1 and 2 can be minimized to make foams hard to be mixed with a bonding agent layer. The lower table 5 is lifted up and moved by the action of an up and down driving mechanism 23 to pressure bond the first material to be bonded 1 and the second material to be bonded 2.
