A BISLACTAMAMIDE DERIVATIVE AS INTERMEDIATE IN THE PRODUCTION OF DI I SOCYANATE |
| 摘要 |
<p>The invention relates to a method for preparing an intermediate compound for a diisocyanate, comprising reacting a diamine represented by the formula H<SUB>2</SUB>N-(CH<SUB>2</SUB>)<SUB>0</SUB>-Y-(CH<SUB>2</SUB>)<SUB>p</SUB>-NH<SUB>2</SUB> wherein Y is selected from CH(OX) or CH(COOX), o and p each are an integer of 0-4, with the proviso that the sum of o and p is 4 or less, preferably 2, 3 or 4, X is a protective group, with a carbonylbislactam, preferably carbonylbiscaprolactam, thereby forming a compound with the formula (I) wherein each L is a lactam from the carbonylbislactam.</p> |
