Синтез и технология получения производных гексаметилен бис [(алкил)-карбаматов]»

Аннотация

Subjects of the inquiry: hexamethelendiisocyanate. Aim of the inquiry: synthesis and technologies of reception an biscarbamates on the basis of spirits, an establishment of their structure, studying of their chemical properties and growth factor activity, highly active substances to recommend to practical application in an agriculture. Methods of inquiry: organic and technological synthesis, the hromatografic analysis, the element analysis; IK-and PMR-spectroscopy, the classical chemical analysis. The results achieved and their novelty: Technologies of reception of new derivatives an hexamethelen bis [(alkyl)-carbamate] are synthesized and developed and their structures are established. For the first time derivatives an bis-carbamates are synthesized: N,N'-dinitrozo, N,N'-dinatrii-, N,N'-dimethel- and N,N'-dihlorreplaced, their structures are established. Connections and their replacements are created new carbamates of N-H groups, in studying which chemical properties the opportunity to develop a new direction on studying chemistry of connections opens. Practical value: On the basis of the primary, secondary and tertiary spirits, being by interesting object the general method of organic synthesis and without waste technology is developed for studying derivatives an bis-carbamates in educational process for practical works of students; as a fundamental problem of technology of organic synthesis; by search new highly effective growth factors, and also less toxical medical products. Degree of embed and economig effectivity: Drug XM-1 XM-2 is tested in three of the Kashkadarinskai range on a cotton plant, corn and a sunflower. Thus economic efficiency on calculation of experts compounds 4,4 mlrd som. Sphere of usage: reagent, growth factor of plants.
