Abstract

 Calcium hypochlorite was laboratorial prepared by bubbling chlorine gas into suspended aqueous slurry solution of locally sourced Ca (OH)2, at constant mass flow rate of 0.4 g/s for time intervals 5 s (5) 20 s at 0.5 atm. The concentration of the preparations varied between 4.16–15.4 g/dm3 corresponding to available chlorine (ACHL) of 51 – 63 %. This range falls favorably with commercial products of solid chlorine from Clear Tech Industries Inc., 2303 Hansel man Avenue, Saskatoon SK S71 5Z3, Canada
 (product produced March 3, 2003; CAS Number 7778-54-3; ACHL, 60-80%). Our results have the potentials of sparking indigenous technology for development of industrial chemicals from our abundant
 local natural solid minerals resources, when the processes involved are optimized
