The invention relates to a method for the intrinsically safe handling of 3- chlorpropyne in the presence of a diluent, which has a boiling point under normal pressure in the range of -50 ~C (223 K) to 200 ~C (473 K). According to the method, the concentration of 3-chloropropyne in the liquid phase and in the gaseous phase is maintained below the concentrations at which deflagration occurs, by means of the type and quantity of the diluent, the temperature and the total pressure of the system. The invention also relates to the use of 3- chloropropyne produced, stored or transported in this manner for the synthesis of dyes, pharmaceutical and agricultural active ingredients, electroplating auxiliary agents, disinfection agents, steroids and growth hormones.
L'invention concerne un procédé permettant de manipuler de manière intrinsèquement sûre du 3-Chloropropyne en présence d'un agent de dilution au point d'ébullition sous pression atmosphérique standardisée compris entre -50 ·C (223 K) et 200 ·C (473 K). Selon ce procédé, la concentration de 3-Chloropropyne dans la phase liquide et dans la phase gazeuse est maintenue en deçà des concentrations auxquelles apparait la déflagration, par la nature et de la quantité de l'agent de dilution, la température et la pression globale du système. L'invention concerne l'utilisation du 3-Chloropropyne ainsi obtenu, stocké et transporté dans la synthèse de colorants, de principes actifs en pharmacie et en agriculture, d'agents auxiliaires galvaniques, d'agents désinfectants, de stéroïdes et d'hormones de croissance.
