摘要:
Compounds of formula (IIa): are provided where:
X is a group capable of being cleaved from the α-carbon atom to form an ion of formula (I')
C is a carbon atom bearing a single positive charge or a single negative charge;
The invention further provides compounds of formula (IIb): where:
X is a counter-ion to C .
The compounds of formula (IIa) and (IIb) may form ions of formula (I') by either cleaving the C-X bond between X and the α-carbon atoms in the case of the compounds of formula (IIa) or dissociating X in the case of compounds of formula (IIb).
摘要:
A method for the preparation of an acrylonitrile solution manifesting transparency, precluding coloration and opacification during the course of handling, and excelling in stability, is provided. The acrylonitrile solution of maleimide is such that, when it is subjected to a forced coloration test, the differences Δ L, Δa, and Δb values (invariably as absolute values) each between L, a, and b values before and after the test are respectively not more than 5, not more than 5, and not more than 10. The acrylonitrile solution of maleimide is prepared by purifying a crude maleimide; applying a primary antioxidant and a secondary antioxidant to the purified maleimide in the molten state; solidifying the molten maleimide by cooling; and subsequently dissolving the solidified maleimide in acrylonitrile.
