Abstract: Purification of triethylene diamine (TEDA) comprises crystallization and extraction of the resulting mother liquor with an extraction agent that is at most only slightly miscible with the solvent of the mother liquor but in which TEDA is soluble. Following extraction, the treated mother liquor with reduced TEDA content and/or the extraction agent enriched in TEDA is recycled to the process. A process for the purification of triethylene diamine (TEDA) by evaporation and feeding the TEDA vapor to a liquid solvent followed by crystallization is characterized in that following crystallization of the TEDA the resulting mother liquor is extracted with an extraction agent that is at most only slightly miscible with the solvent of the mother liquor but in which TEDA is soluble. Following extraction, the treated mother liquor with reduced TEDA content and/or the extraction agent enriched in TEDA is recycled to the process.

Abstract: Positive-working radiation-sensitive mixt. is based on (a) either (a-1) water-insol. organic polymeric binder(s) with acid-labile gps., rendered soluble in aq. alkaline soln. by the action of acid or (a-2.1) a water-insol. polymeric binder, which is soluble in aq. alkaline soln., and (a-2.2) a low mol. organic cpd., which is rendered more soluble in an aq. alkaline developer by the action of an acid; (b) organic photo-acid(s); and opt. (c) organic cpd(s). other than (b). The novelty is that at least one of (a-1), (a-2.1), (a-2.2), (b) and (c) contains a gp. of formula -O N -R4 (I) or (c) is of formula O-CO-Ä(CH2Ün-CH2-N R3 (II); in which R = 1-6 C alkyl; n = 1-6.

Abstract: Azulene methine dyestuffs of formula (I) are used in electrophotography and in the prodn. of photoresists and printing plates where R = (substd.) 1-6C alkyl; X- = an anion; A+ = a heterocyclic gp.; n = 1, 2 or 3; m = 1 or 2. The prepn. of (I) (not claimed) is described e.g. in EP-338426. USE/ADVANTAGE - Used as charge carrier generating cpd. or sensitiser in electrophotographic recording elements, pref. of the multilayer type, esp. for making (offset) printing plates, photoresist patterns or photocopiers by reprography. Suitable for exposure with UV, visible, red and IR light, e.g. with a semiconductor laser, and gives excellent results. (Dwg.0/0)

Abstract: Procedimiento para la purificación de trietilendiamina (TEDA), en el que la TEDA se evapora y la TEDA en estado de vapor se hace pasar a través de un disolvente líquido y, a continuación, se separa por cristalización a partir del mismo, caracterizado porque las lejías madre, obtenidas tras la separación por cristalización de la TEDA, se extraen con un agente de extracción, que no sea miscible, o que únicamente sea poco miscible, con el disolvente de las lejías madre y en el que se disuelva perfectamente la TEDA, y se reciclan hasta el procedimiento las lejías madre, empobrecidas en TEDA, obtenidas tras la extracción y/o el agente de extracción enriquecido con TEDA, empleado para la extracción.
