    摘要: A method for producing aldehydes, which comprises reacting an olefinic unsaturated compound with carbon monoxide and hydrogen in a liquid phase in the presence of a Group 8 metal-phosphite complex catalyst, wherein a reaction product solution containing the complex catalyst and a high boiling by-product, obtained by the reaction, is intimately contacted with an extraction solution containing a polar solvent, to have either the complex catalyst or the high boiling by-product extracted selectively, followed by phase separation to separate a layer of the extraction solution from a layer of the reaction product solution.

    摘要: An adhesive filler apparatus is disclosed comprising an injector and a support portion, the injector comprising a pressure buffer tube made of elastic material and a check valve adjacent one end of the pressure buffer tube, the support portion comprising a base member and a projection. The adhesive filler apparatus disclosed is used as follows: An adhesive is fed through a hose connected to a pump, etc. in the pressure buffer tube, causing the tube to swell. The hose is disconnected from the injector, causing the check valve to close the end of the tube. The fed injector is coupled to the support portion fixed on the crack of a concrete structure, etc., whereupon the projection on the support portion presses the check valve to open the end of the fed tube, thereby allowing the adhesive in the tube to be filled in the crack by gradual and continuous contraction of the elastic tube.
