| titleOfInvention | Method for the production of 1,4-butandiol from maleic anhydride |
| abstract | 1. Catalytic process for the preparation of 1,4-butanediol from maleic anhydridenhydrogenation in the presence of an aliphatic alcohol Ci-C4 in the vapor phase, characterizednin that the process is carried out in two stages, the anhydride in the first stagenmaleic, aliphatic alcohol and hydrogen, in amounts greater than stoichiometric,nare introduced into a reactor where they are brought into contact with a copper-nickel catalystnor platinum or palladium at a temperature of 150-250 ° C, preferably 170-230 ° C, undernpressure of 2-10 MPa, and the thus obtained hydroesterificate, after isolating thenmonoesters, is directly hydrogenated on a copper-zinc catalyst,nat a temperature of 150-250 ° C, preferably 200-230 ° C, under a pressure of 2-10 MPa, ponwhereby 1,4-butandiol is separated from the post-reaction mixture by known methods. |
