Title (EN) LESS COLORED TRANS-1,3-DICHLOROPROPENE AND PROCESS FOR PRODUCING THE SAME
(FR) TRANS-1,3-DICHLOROPROPENE A MOINDRE COLORATION ET PROCEDE DE PREPARATION
Abstract: front page image
(EN)Less colored trans-1,3-dichloropropene and a process for producing it. A composition comprising cis-1,3-dichloropropene, trans-1,3-dichloropropene, and a C¿6? compound is subjected to a distillation step and to the step of causing chlorine or bromine to act. Thus, the cis-1,3-dichloropropene is removed as a low-boiling matter. The resultant residue is distilled. Thus, the C¿6? compound which has been chlorinated is removed as a high-boiling ingredient and the trans-1,3-dichloropropene is obtained as a low-boiling ingredient.
(FR)Cette invention a trait à un trans-1,3-dichloropropène à moindre coloration et au procédé de préparation de celui-ci. On distille, dans le cadre de ce procédé, une composition renfermant un cis-1,3-dichloropropène, un trans-1,3-dichloropropène et un composé porteur de 6 atomes de carbone et on la soumet à une étape au cours de laquelle on fait agir du chlore ou du brome. Le cis-1,3-dichloropropène est alors extrait en tant que substance à bas point d'ébullition. On distille ensuite le résidu résultant. On retire ensuite le composé porteur de 6 atomes de carbone ayant été chloré en tant qu'ingrédient à point d'ébullition élevé et l'on obtient du trans-1,3-dichloropropène comme ingrédient à bas point d'ébullition.
