Oser, H.Several substances are used for example 19398-61-9 and 91-20-3 which are their cas registry numbers.; Thanner, R.; Grotheer, H. H. (Institute Physical Chemistry Combustion, Stuttgart D-70569, Germany). Combustion Science and Technology, 116-117(1-6), 567-582 (English) 1996 Gordon & Breach. CODEN: CBSTB9. ISSN: 0010-2202. DOCUMENT TYPE: Journal CA Section: 48 (Unit Operations and Processes) Section cross-reference(s): 59 A resonance enhanced multiphoton ionization (REMPI) mass spectrometer was presented which combines high sensitivity with very low cross-sensitivity. The sensitivity of the instrument was increased by shifting the ionization regime close to the continuous ("jet") portion of the sample beam. A further gain in sensitivity was achieved by increasing the ionization vol. by a complete re-design of the ion source. A very low base-line level was achieved by using a geometry which prevents secondary ionization by the collision of ions/electrons with surfaces. These improvements resulted in an excellent performance from the app., which was demonstrated by dichlorotoluene and naphthalene spectra which were obtained under a variety of conditions. The detection limit of naphthalene was 5 ppt (mole fraction) for a S/N = 1. The method can be used to monitor trace compds. in gases (e.g., as candidate incomplete oxidn. products) for control of municipal waste incinerators. .

(Japan). CODEN: JKXXAF. CLASS: IC: C07C025-02; B01J029-06; C07C017-24. APPLICATION: JP 82-27279 24 Feb 1982. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Polyhaloarom. compds. were isomerized by contacting with zeolites (acid form). 19398-61-9 and 120-82-1 are cas registry numbers of chemicals which are used as reagents here. Thus, o-Cl2C6H4 was passed over zeolite ZSM 5 (acid form) at 350° and 30 kg/cm2 to give a product contg. o- 39.4%, m- 43.4% and p-Cl2C6H4 17.2%. Similarly, 2,4-Cl2C6H3Me and mordenite-type zeolite gave 2,4-, 3,5-, 2,5-, 3,6-, 3,4- and 2,3-Cl2C6H3Me. .
