Abstract:
The invention relates to various fields of medicine, pharmaceutics and pharmacology, chemico-pharmaceutical, pharmaceutical and para-pharmaceutical industries, and in particular to new class of agents having modulatory activity with commensurate effect. The invention consists in that provided product (RS)-2-(2-oxo-4-phenylpyrrolidin-1-yl)acetamide does not contain biologically inert substances in its composition having adverse effect on its newly discovered and considerably improved known properties and characteristics, at the same time discovering unknown before vitally important and essential ideas about the composition, widening the field of its application while increasing its efficiency and safety of use, increasing its therapeutic scope, provides for preparing the product and its products with revealed properties and characteristics.
Abstract:
The invention relates to a method for storing and transporting N-vinyl-ε-caprolactam, which is characterized by maintaining the N-vinyl-ε-caprolactam in the liquid phase.
Abstract:
Process for the preparation of an N-alkyl lactam with improved colour quality, where 0.01 to 10% by weight of a C1-10-alcohol or a compound which releases 0.01 to 10% by weight of a C1-10-alcohol is added to the N-alkyl lactam. Mixture comprising at least 99.0% by weight of an N-alkyl lactam and in the range from 100 to 5000 ppm by weight of a C1-10-alcohol or of an acetal, aminal or an ortho ester which releases in the range from 100 to 5000 ppm by weight of a C1-10-alcohol.
