| titleOfInvention | METHOD FOR MANUFACTURING BIS- (ISOCYANATOMETHYL) -TRICYCLO-SQUARE CLAMP TO DECANEN ON 5.2.1.0 HIGH 2.6-ANGLE CLAMP |
| abstract | Bis-(isocyanato-methyl) tricyclo- 5,2,1,O2,6 decane isomers are made by neutralising 3 or (4), 8 or (9)-bis(amino-methyl)tricyclo- 5,2,1,O2,6 decanes (II) in inert solvent with CO2, while exposed as a thin film with large surface area, and subsequently reacting the suspension with phosgene. Used as low-volatility diisocyanates for polyurethane prodn. Low-viscosity suspensions are obtd. which react readily with phosgene, without heating during neutralisation or subsequent ageing. Neutralisation is pref. carried out in one or more thin-film reactors, e.g. wide glass tubes with the (II) soln. flowing down the inner wall and exposed to CO2, while the tube is cooled by an outer jacket. Suitable solvents are aliphatic, cycloaliphatic or opt. halogenated aromatic hydrocarbons and esters, esp. chlorobenzene. Phosgenation is pref. at 0.30 degrees C in a stirred reactor. |
