摘要: 1. A PROCESS FOR THE MANUFACTURE OF 3-PENTENENITRILE WHICH COMPRISES REACTING AT A TEMPERATURE WITHIN THE RANGE -25* C. TO 200* C. A MIXTURE OF BUTADIENE, HYDROGEN CYANIDE AND, AS SOLE CATALYST, A COMPLEX OF CUPROUS CHLORIDE, BROMIDE OR IODIDE WITH AN ORGANIC NITRILE SELECTED FROM 3-PENTENENITRILE AND COMPOUNDS HAVING NITRILE GROUPS ATTACHED TO A SATURATED OR ETHYLENICALLY UNSATURATED HYDROCARBON RESIDUE CONTAINING UP TO THREE CARBON ATOMS, THE SAID CATALYST BEING USED IN THE AMOUNT OF 0.0005 TO 0.1 MOLE PER MOLE OF BUTADIENE, THE MOLAR RATIO OF BUTADIENE TO HYDROGEN CYANIDE BEING 2:1 TO 1:4, AND THE CATALYST COMPLEX BEING FORMED BY MIXING THE SAID CUPOROUS SALT WITH THE SAID ORGANIC NITRILE BEFORE OR AT THE SAME TIME AS IT IS MIXED WITH THE BUTADIENE AND HYDROGEN CYANIDE.
