Enwere usoro mmepụta abụọ nke calcium chloride , otu bụ usoro acid na nke ọzọ bụ usoro alkali.
A na-akwado usoro acid ahụ site na mmeghachi omume kemịkalụ nke limestone na hydrochloric acid. A na-eji ihe dị ka 22% dilute hydrochloric acid meghachi omume na nkume limestone (nwere ihe dịka 52% calcium) iji mepụta 27% mmiri mmiri calcium chloride. Mgbe nzacha na nkewa, a na-atụfu ihe fọdụrụ nzacha. A na-ewepụ ihe nzacha ahụ na mmiri ara ehi lime iji dozie pH = 8.9-9. Ihe ndị na-adịghị ọcha na ngwọta calcium chloride dị ka m, Fe, al1, wdg na-etolite m (OH) 2, Fe (OH) 3, A1 (OH) 3, wdg na-ebuli. Achịcha nzacha bụ ihe mkpofu siri ike, A na-edobe ihe nzacha ahụ na-enwe mmetụta atọ na-amanye na-ekesa ikuku evaporation iji tinye 27% calcium chloride ngwọta na 68-69%, wee tinye ya n'ime flaker maka mmepụta. A na-akpọnwụ calcium chloriden'ime akwa mmiri na-emepụta 74% calcium chloride dihydrate
Usoro Alkali na-emepụta calcium chloride: 1. Direct evaporation usoro nke calcium chloride: n'ozuzu, ọdịnaya nke calcium chloride na n'efu mmanya nke soda ash bụ 76.8g/l. Mgbe emechara ya dị ọcha, a na-ebu ụzọ tinye ya, kewapụ kristal na-abaghị uru, wee gbado anya inweta calcium chloride.
2. Calcium chloride nnu ubi tupu evaporation usoro: n'ozuzu, nnu ubi-agbasa na-eji ndammana evaporate na soda ash n'efu mmiri mmiri. A na-edozi nnu dị n'ime mmiri mkpofu, na nnu dị n'ime mmiri mkpofu ga-ebu ụzọ mee ngwa ngwa. Site na mmụba nke evaporation, ọtụtụ nnu ga-ebuli elu. A ga-anakọta mmiri mmiri calcium chloride fọdụrụnụ n'ime akụrụngwa maka ikuku, a ga-enwetakwa calcium chloride.
Ihe dị iche n'etiti usoro mmepụta abụọ bụ na ike nke calcium chloride nke usoro acid na-emepụta dị elu karịa nke ahụ site na usoro alkali, ma enwere ọtụtụ adịghị ọcha, agba agba na ekpomeekpo, na usoro acid dị ọnụ ala karịa usoro alkali. Mbadamba nkume Calcium chloride nwetara site na usoro alkali dị gịrịgịrị ma na-emebi emebi, nwere ịdị ọcha dị elu, adịghị ọcha ole na ole na agba ọcha.
