Abstract
Invenţia se referă la un procedeu de preparare a diclorurii bis(2-cloretil)amidofosfonice şi constituie o perfecţionare a invenţiei cu descrierea nr. 84601. Procedeul conform invenţiei constă în aceea că mediul de reacţie toluenic rezultat în urma reacţiei dintre oxiclorura de fosfor şi clorhidratul de bis(2-cloretil) este însămânţat cu germeni de cristalizare şi răcit la aproximativ -10°C, sub agitare, după care se filtrează rapid, la temperatură ambiantă şi presiune atomosferică. Procedeul conform invenţiei permite diminuarea pierderilor de solvent ca urmare a antrenării acestuia în timpuldistilării, iar produsul se obţine cu randament îmbunătăţit şi cu o puritate avansată.The invention relates to a process for the preparation of bis (2-chloroethyl) amidophosphonic dichloride and constitutes an improvement of the invention with the specification no. 84601. The process according to the invention consists in that the toluene reaction medium resulting from the reaction between phosphorus oxychloride and bis (2-chloroethyl) chloride is seeded with crystals and cooled to about -10 ° C with stirring, is rapidly filtered at ambient temperature and atomospheric pressure. The process according to the invention allows to reduce the losses of solvent as a result of its entrainment during the distillation, and the product is obtained in improved yield and with advanced purity.
