Higher Degree Decomposition of Harmful Organic Compounds Containing Chlorine by Using Molten Salts

Determination of chlorine in organic compounds containing mercury

The standard procedure for the determination of chlorine in organic compounds of mercury consists in decomposition of the material, separation of mercury and determination of chlorine as chloride. Decomposition of the sample could be achieved by wet mineralization [1,2], ignition in a stream of oxygen [3—7] or nitrogen [8], ignition in a flask with oxygen [9], etc. [10, 11]. Chlorine and mercur...

Polarography in Molten Salts

TYPES OF MELTS From the practical viewpoint, melts may be classified according to melting points which may limit the available techniques. The lowest melting, with working temperatures up to 250°, are typified by the LiNO3—NaNO3— KNO3 eutectic, NaNO3—KNO3 eutectic, LiClO4, and ammonium formate. With these solvents it is possible to use the dropping mercury electrode, or hanging mercury drop ele...

Halogenated volatile organic compounds in chlorine-bleach-containing household products and implications for their use

CHCl3 and CCl4 were the dominating halogenated VOCs in chlorine bleach products. Indoor air VOC estimates indicated substantial increases from bleach use. Carcinogenic risks from the use of bleach products may be considerably high. a r t i c l e i n f o

ORGANIC CHEMISTRY Organic Compounds containing Nitrogen

Molecular ordering of organic molten salts triggered by single-walled carbon nanotubes.

When mixed with imidazolium ion-based room-temperature ionic liquid, pristine single-walled carbon nanotubes formed gels after being ground. The heavily entangled nanotube bundles were found to untangle within the gel to form much finer bundles. Phase transition and rheological properties suggest that the gels are formed by physical cross-linking of the nanotube bundles, mediated by local molec...
