IPC: C07C29/158
Filed: 1984-08-02
Abstract: PURPOSE:To prepare ethylene glycol efficiently from a synthesis gas under relatively mild conditions, by reacting the synthesis gas in the presence of a rhodium-containing compound catalyst, a specific trialkylphosphine and aliphatic monocarboxylic acid. CONSTITUTION:Synthesis gas, i.e. a mixed gas of carbon monoxide and hydrogen is reacted to give ethylene glycol. In the process, the reaction is carried out in the presence of a rhodium-containing compound, e.g. tetrarhodium dodecacarbonyl, in 1X10<-6>-100g atoms, particularly 1X10<-5>-10g atoms, based on 1l reaction solution concentration of Rh atoms in the reaction solution, a trialkylphosphine in which the alpha-carbon of the phosphorus atom is methyl or secondary carbon atom, e.g. tri-n-butylphosphine, at 2-500, particularly 5-300 molar ratio to the Rh atoms and an aliphatic monocarboxylic acid, e.g. formic acid or acetic acid, at 0.1-200, particularly 0.5-100 molar ratio to the Rh atoms.

Title: Separable screw
Inventor: YAMADA IKUFUMI
IPC: A61F2/62
Filed: 1994-06-09
Abstract: PURPOSE:To provide a separable screw capable of removing the tip section of the screw after a ligament is fixed for making the ligament hard to be cut by removing the tip section after insertion not to damage the implanted ligament so that the tip of a body section does not damage the implanted ligament. CONSTITUTION:A tip section 1 has an insertion section 5 into a body section 2, and a screw is integrated when it is inserted. When the insertion section 5 is a hexagonal pillar, the portion 6 of the body section 2 to be inserted with the insertion section 5 has a hexagonal cross section. When the body section 2 has a rotating structure, the tip section 1 also has a rotating structure. After the screw is inserted into a bone hole and a ligament is fixed, the tip section 1 is extruded and removed with an extruding tool. Since the tip 4 of the body section 2 has a spherical structure 9, the ligament is hardly cut as compared with the case that the tip section 1 is left even when the ligament is moved into contact with the spherical structure 9. The tip section 1 and the body section 2 have common holes, a guide wire is inserted into them, and the tip section 1 can be surely removed without being bewildered when the tip section 1 is removed after the ligament fixed.
