Process of sanitizing swimming pools, spas and, hot tubs

A sanitizing composition for aqueous solutions comprising an dialiphatic dimethylammonium salt having an effective bactericidal activity at a concentration below about 50 ppm by weight in the medium to be sanitized during a maximum contact time not exceeding 60 seconds.

Treatment for sanitizing aqueous solutions

Aromatic hydrocarbons are readily recovered from aqueous solutions by contacting the aqueous solution with an oxidized activated carbon having a low concentration of acidic oxides. The novel oxidized activated carbon is produced by contacting activated carbon with an acidic oxidizing agent which is used in low concentrations. The process can be employed to reduce aromatic hydrocarbons such as benzene from aqueous solutions such as industrial effluents or potable water supplies to levels permissible by environmental protection regulations.

Oxidized activated carbon and its use in removal of aromatic compounds

Disclosed is a process for producing pentachloronitrobenzene (PCNB) by reacting hexachlorobenzene (HEX) with sodium hydrosulfide (NaSH) in the presence of sodium hydroxide (NaOH), sodium carbonate (Na.sub.2 CO.sub.3), or mixtures thereof to produce the sodium salt of pentachlorothiophenol (PCTP), followed by reacting it (or PCTP itself after acidifying) with nitric acid in the presence of sulfuric acid or oleum.
