| Iimpawu ezinobungozi | C – Iyadleka |
| Iikhowudi zoMngcipheko | I-R21/22 – Iyingozi xa udibana nolusu kwaye ukuba uginyiwe. I-R35 – Ibangela ukutshisa okumandundu R48/22 – Ingozi eyingozi yomonakalo omkhulu empilweni ngokuba sesichengeni ixesha elide ukuba iginyiwe. |
| Inkcazelo yoKhuseleko | S23 – Musa ukuphefumla umphunga. S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S28 – Emva kokudibana nolusu, hlamba ngoko nangoko ngeesepha ezininzi. S36/37/39 – Nxiba iimpahla ezifanelekileyo zokukhusela, iiglavu kunye nokukhusela amehlo/ubuso. S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) |

Intshayelelo
I-S-(-)-2-chloropropionic acid yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Iipropati: S-(-)-2-chloropropionic acid lulwelo olungenambala nevumba elibi. Iyanyibilika emanzini nakwi-ethanol kwaye ayinyibiliki kwi-ether. Kwiqondo lobushushu begumbi, inoxinzelelo oluphakathi lomphunga.
Ukusetyenziswa: S-(-) -2-chloropropionic acid isetyenziswa ngokuqhelekileyo njenge-reagent, i-catalyst kunye ne-intermediate in organic synthesis.
Indlela yokulungiselela: Kukho iindlela ezimbini eziphambili zokulungiselela i-S-(-)-2-chloropropionic acid. Enye indlela kukufumana ityuwa yesodium ye-S-(-) -2-chloropropionate ngokusabela kwe-phenylsulfonyl chloride kunye ne-sodium ethanol albutan, kwaye emva koko i-acidify ukwenza imveliso ekujoliswe kuyo. Enye indlela kukucoca nge-hexanone kunye ne-hydrogen chloride phambi kwe-oxidant, ilandelwa yi-acidification ukufumana imveliso ekujoliswe kuyo.
Ulwazi ngokhuseleko: I-S-(-)-2-chloropropionic acid iyacaphukisa kwaye kufuneka iphetshwe xa idibana nolusu namehlo. Izixhobo ezifanelekileyo zokukhusela, ezinjengeeglavu kunye neeglavu, kufuneka zinxitywe xa usebenza. Gcina kwindawo engenamoya, kude nomlilo kunye nee-oxidants.
