(S)-a-chloropropionic acid (CAS#29617-66-1)
| Izimpawu Eziyingozi | C – Iyabola |
| Amakhodi Engozi | R21/22 – Kuyingozi ukuthinta isikhumba futhi uma ugwinyiwe. R35 – Idala ukusha kanzima R48/22 – Ingozi eyingozi yokulimala kabi empilweni ngokuchayeka isikhathi eside uma igwinywe. |
| Incazelo Yokuphepha | S23 – Ungawuphefumuli umhwamuko. S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. I-S28 – Ngemva kokuxhumana nesikhumba, geza ngokushesha ngensipho eningi. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) |

Isingeniso
I-S-(-)-2-chloropropionic acid iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Izakhiwo: I-S-(-)-2-chloropropionic acid iwuketshezi olungenambala olunephunga elimnandi. Iyancibilika emanzini ne-ethanol futhi ayincibiliki ku-ether. Emazingeni okushisa asekamelweni, inomfutho womoya omaphakathi.
Ukusetshenziswa: I-S-(-)-2-chloropropionic acid ivame ukusetshenziswa njenge-reagent, i-catalyst kanye ne-intermediate ku-organic synthesis.
Indlela yokulungiselela: Kunezindlela ezimbili eziyinhloko zokulungiselela i-S-(-)-2-chloropropionic acid. Enye indlela ukuthola usawoti we-sodium we-S-(-)-2-chloropropionate ngokusabela kwe-phenylsulfonyl chloride ne-sodium ethanol albutan, bese uyifaka i-asidi ukuze wenze umkhiqizo oqondiwe. Enye indlela iwukucwenga nge-hexanone ne-hydrogen chloride phambi kwe-oxidant, kulandele i-acidification ukuze kutholwe umkhiqizo okuhlosiwe.
Ulwazi lokuphepha: I-S-(-)-2-chloropropionic acid iyacasula futhi kufanele igwenywe ukuthintana nesikhumba namehlo. Izimpahla zokuzivikela ezifanele, njengamagilavu nezibuko, kufanele zigqokwe lapho usebenza. Gcina endaweni engenamoya, kude nomlilo nama-oxidants.
