Abstract: What is provided herein is a stable, emulsifiable gel matrix for an agriculturally active chemical, which matrix will form an emulsifiable gel concentrate upon addition of the agriculturally active chemical, and upon water dilution, a highly stable aqueous macroemulsion which avoids precipitation of the active ingredient on extended storage. In addition, the inventive emulsifiable gel concentrates may contain relatively high concentrations of the agriculturally active chemical, the concentration sometimes being referred to as "loading", making it advantageous from both the economic and handling viewpoints. In one embodiment, the emulsifiable gel matrix comprises a surfactant (nonylphenol ethoxylated phosphate ester), a solvent system (N-methylpyrrolidone + N-octylpyrrolidone), a thickening agent (hydroxypropyl cellulose), a high molecular weight polymer as a viscosity enhancer and/or disintegration aid (polyvinylpyrrolidone), and optionally a polyhydric alcohol (glycerol) and an organic diluent (naphtha and other aromatic oils).

Abstract: This invention relates to a process for the purification of a crude liquid N-vinylpyrrolidone product which comprises (I) product rectification by (a) subjecting said crude product containing at least 0.3 weight % of impurities to a temperature of between about 1 DEG and 5 DEG below the freezing point of said crude liquid to form a vinyl pyrrolidone crystalline phase and a liquid residue phase in a first crystallization step; (b) separating said liquid phase from said crystalline phase; (c) allowing said separated crystalline phase to warm gradually so as to liquify said crystals and (d) subjecting the liquified crystals of vinyl pyrrolidone to between 1 and 3 additional crystallization steps, each carried out by gradually cooling the liquified vinyl pyrrolidone to a temperature above that of the preceding crystallization step up to a temperature of 14.4 DEG C so as to form additional vinyl pyrrolidone crystalline and liquid residue phases with separation of vinyl pyrrolidone crystals and liquid residue phases and liquification of vinyl pyrrolidone crystals between each additional recrystallization step, recovery of N-vinyl-pyrrolidone product from the final crystallization step and (II) collecting said separated liquid residues from each crystallization step and subjecting them, sequentially, individually or collectively, to fractional crystallization in order to recover additional amounts of purified vinyl pyrrolidone product. The present process is capable of achieving up to 99.999 % purity of vinyl pyrrolidone in about 98 % recovery.
