Abstract: The invention relates to a process for increasing the selectivity of the hydrogenation of 4,4'-diaminodiphenylmethane (4,4'-MDA) to diaminodicyclohexylmethane (4,4'-HMDA) by catalytic hydrogenation of a mixture containing 4,4'-MDA as the main component and its mono-N-methyl derivative as a secondary component. According to the invention, the hydrogenation is terminated before a conversion of 4,4'-MDA to 4,4'-HMDA of 99% is achieved. Under these conditions, a substantially smaller proportion of the N-methyl-4,4'-MDA is hydrogenated to N-methyl-4,4-HMDA.

Abstract translation: 本发明涉及通过催化氢化含有4,4'-二氨基二苯基甲烷（4,4'-MDA）的混合物的方法提高4,4'-二氨基二苯基甲烷（4,4'-MDA） MDA为主要成分，其单-N-甲基衍生物为次要成分。 根据本发明，在将4,4'-MDA转化为99％的4,4'-HMDA之前终止氢化。 在这些条件下，将大部分比例的N-甲基-4,4'-MDA氢化成N-甲基-4,4-HMDA。

Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of obtaining a desired alicyclic isocyanate with a high selectivity. SOLUTION: The method comprises reacting an aromatic isocyanate with hydrogen in the presence of a supported catalyst containing ruthenium alone as the active metal or together with at least one metal of subgroup I, VII and VIII metals in the periodic table in an amount of 0.01-20 mass%, the catalyst carrier having a BET surface area of 30 m 2 /g to less than 70 m 2 /g and not less than 50 % of the pore volume of the catalyst carrier being micropores having a pore diameter of greater than 50 nm and less than 50 % of the pore volume of the catalyst carrier being micropores having a pore diameter of 2-50 nm. According to this method, a desired isocyanate can be obtained with a high selectivity and the ratio of the 4,4'-trans-trans-isomer is low and in this instance, the low 4,4'-trans-trans-isomer ratio can be maintained in spite of a high degree of conversion. The catalyst life is long and, simultaneously, and the isomer distribution hardly changes even after a considerably long-term operation. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a method for hydrogenating an aromatic urethane, and to provide use of a supported catalyst.
SOLUTION: This method for hydrogenating the aromatic urethane comprises reacting the aromatic urethane with hydrogen in the presence of the supported catalyst, wherein the supported catalyst is formed by supporting 0.01-20 wt% of ruthenium as an active metal solely or together with at least one kind of the subgroup I, VII, and VIII metals in the periodic table on such a carrier for the catalyst that a BET surface area of the carrier is not less than 30 m
2 /g but less than 70 m
2 /g, 50% or more of pore spaces of the carrier comprise macro-pores having a pore diameter of more than 50 nm, and less than 50% of pore spaces comprise meso-pores having a pore diameter of 2-50 nm. thus, a desired aliphatic urethane is obtained with high selectivity, so that a ratio of a 4,4'-trans-trans-isomer in bis(isocyanatocyclohexyl)methane (H
12 MDU) is low. Further, the low ratio of the 4,4'-trans-trans-isomer is kept, while a rate of the reaction is high. The catalyst has a long life, and distribution of the isomers is approximately unchanged, even when an operation time of a relative long period has been elapsed.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing isophoronediamine from isophoronenitrile, comprising hydrogenating in the presence of a Raney catalyst having a small apparent density and a good hydrogenation activity. SOLUTION: This method for producing the isophoronediamine from isophoronenitrile, isophoronenitrileimine and/or their mixture comprises hydrogenating into the isophoronediamine in the presence of at least ammonia, hydrogen, and a hollow type Raney hydrogenation catalyst based on at least cobalt, nickel, copper and/or iron. The production of the isophoronediamine in a high conversion and in an extremely good yield can be achieved using substantially small amounts of the catalyst materials, because the apparent density of the catalyst is small.
