Ithetha ntoni inombolo yeCAS? Uhlalutyo olubanzi “lwamakhadi ezazisi” kwishishini lemichiza
Kwishishini lemichiza, sihlala sidibana nekota yenombolo ye-CAS, eyona nto ibalulekileyo kwinkcazo yemveliso, kugcino lweenkcukacha zeekhemikhali kunye nemisebenzi yemihla ngemihla. Nokuba kwiinkcukacha zemveliso, kugcino lweenkcukacha zemichiza, okanye kwimisebenzi yemihla ngemihla yeenkampani zekhemikhali, inombolo ye-CAS sisiphawuli esiphambili.Ithetha ntoni inombolo ye-CAS? Eli nqaku liza kukunika impendulo eneenkcukacha.
Yintoni inombolo yeCAS?
Inombolo ye-CAS (iNombolo yeNkonzo yeeNgcaciso zeMichiza) sisichongi esikhethekileyo esinikwe yiNkonzo yeeNgcaciso zeMichiza (CAS). Ikhemikhali nganye, nokuba iyenzeka ngokwemvelo okanye yenziwe, inenombolo eyodwa ye-CAS, evumela ukuba zichongwe ngokuchanekileyo kwaye zilandelelwe kwihlabathi liphela.
Ubume kunye neempawu zenombolo ye-CAS
Inombolo yeCAS idla ngokuba ngamalungu amathathu amanani, umzekelo 64-17-5, emele ulwazi olwahlukileyo:

Inxalenye yokuqala, enokwahluka ukusuka kumanani amabini ukuya kwasixhenxe, ichaza inani elikhethekileyo lemichiza;
Icandelo lesibini lihlala linani elinemivo emibini, elisetyenziselwa ukulinganisa inxalenye yokuqala;
inxalenye yesithathu yidijithi yokutshekisha enye, esetyenziselwa ukuqinisekisa ukuchaneka kweendawo ezimbini zokuqala zenani.

Esi sakhiwo sivumela iinombolo ze-CAS ukuba ziphephe ukuphindaphinda kwaye zibonelela ngendlela esemgangathweni yokuchonga izinto zekhemikhali.
Ukusetyenziswa kunye nokubaluleka kwamanani e-CAS
Nje ukuba siqonde ukuba inani le-CAS lithetha ntoni, kufuneka siqonde ukuba isetyenziselwa ntoni na. eyona njongo iphambili yenombolo ye-CAS kukuqinisekisa ukuba ikhemikhali iyodwa kwaye ibonwa kwihlabathi jikelele. Ekubeni izinto zeekhemikhali zinokuba namagama amaninzi kunye ne-aliases, ukusetyenziswa kwenombolo ye-CAS kugwema ukudideka. Ngokomzekelo, i-Ethanol inokubizwa ngokuba yi-alcohol, i-ethyl alcohol, njl kwiimeko ezahlukeneyo, kodwa inombolo yabo ye-CAS 64-17-5 iyodwa, eqinisekisa ukuba akukho ukungaqondi kakuhle xa unxibelelana phakathi kweelwimi ezahlukeneyo kunye nemimandla.
Amanani e-CAS adlala indima ebalulekileyo ekuthengeni, ekuthengisweni, kuphando nakulawulo lolawulo kwishishini lemichiza. Ngokomzekelo, kwii-Safety Data Sheets (SDS), iinombolo ze-CAS zisetyenziselwa ukuchonga ngokucacileyo izinto zekhemikhali ezibandakanyekayo ukwenzela ukuba amaqela anomdla azi kakuhle ukuba yintoni iipropati zezinto kunye nobungozi obunokwenzeka.
Ukufumana kunye nokuBuza iinombolo zeCAS
Ukuba ufuna ukukhangela inombolo ye-CAS yezinto zekhemikhali, unokukhangela kwiinkcukacha ezininzi zeekhemikhali ze-intanethi, ezifana neRegistry yeCAS, iPubChem, kunye nezinye. Ezi nkcukacha zolwazi zibonelela ngobutyebi bolwazi kwizinto zekhemikhali, kubandakanywa neenombolo zabo zeCAS, izakhiwo zemolekyuli, iipropathi zekhemikhali, nokunye.
Kwiinkampani, ukuba neenombolo ezichanekileyo ze-CAS azincedi kuphela ulawulo lokuthotyelwa, kodwa ziphucula ukusebenza kakuhle kolawulo lwekhonkco lokubonelela. Umzekelo, ukuqinisekisa ukuba imathiriyeli ekrwada ethengiweyo iyafana ncam nemichiza efunekayo ukunqanda imiba yobulunga okanye imingcipheko yolawulo.
Ukuqukumbela
Impendulo kumbuzo wokuba inani le-CAS lithetha ukuthini lihamba ngaphaya kwentsingiselo yalo yokwenyani ukuya kwindima yalo engenakubuyiselwa kwishishini lemichiza, apho lisebenza 'njengekhadi lesazisi' kwizinto zekhemikhali, ziqinisekisa ukuchongwa kwazo ngokuchanekileyo kunye nolawulo kwinqanaba lehlabathi. Ukuqonda nokusebenzisa ngokuchanekileyo amanani e-CAS sisakhono esibalulekileyo kwabo basebenza kushishino lweekhemikhali.
