Abstract

Se preparo polisuccinimida al hacer reaccionar gas de amoniaco con anhídrido maléico líquido. La reaccion se llevo a cabo inicialmente a una temperatura la cual está por arriba del punto de fusion del anhídrido maléico, pero por abajo del punto de ebullicion del anhídrido maléico líquido por un período de tiempo suficiente para que el anhídrido maléico líquido reaccione con el gas de amoniaco para formar un producto de reaccion del mismo. El producto de reaccion se polimerizo subsecuentemente a polisuccinimida. El presente método evita los problemas de la técnica anterior de retirar el agua y minimiza la necesidad de equipo de manejo del amoniaco. El producto de polisuccinimida puede ser fácilmente hidrolizado a ácido aspártico o una sal del mismo, si se desea.
