| Iikhowudi zoMngcipheko | I-R20/22 – Iyingozi ngokuphefumla kwaye ukuba iginywe. I-R34 – Ibangela ukutsha R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. I-R20 – Inobungozi ngokuphefumla R52/53 – Iyingozi kwizinto eziphila emanzini, inokubangela iziphumo ezibi zexesha elide kwindawo ehlala emanzini. I-R43 – Inokubangela uvakalelo ngokudibana nolusu I-R41 – Umngcipheko womonakalo omkhulu emehlweni I-R38 – Iyacaphukisa ulusu I-R20/21/22 – Iyingozi ngokuphefumla, xa udibana nolusu naxa uginyiwe. |
| Inkcazelo yoKhuseleko | S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango.

Intshayelelo
I-3-(methylthio) propionaldehyde yikhompawundi ephilayo,
Umgangatho:
- Imbonakalo: 3-(methylthio)propionaldehyde lulwelo olungenambala ukuya kumthubi.
- Ivumba: linevumba elirhabaxa nelihlabayo lesalfure.
- Ukunyibilika: Ukunyibilika emanzini kunye nezinyibilikisi eziphilayo.
Sebenzisa:
- 3-(methylthio) propionaldehyde isetyenziswa ikakhulu njenge-reagent ebalulekileyo kwi-organic synthesis.
Indlela:
- I-3-(methylthio) propionaldehyde inokulungiswa ngoluhlu lweendlela zokudibanisa. Ngokomzekelo, inokufumaneka nge-malonitrile ngokusabela nge-hydrogen sulfide kwaye emva koko nge-thionylation chloride. Ezinye iindlela ziquka ukusetyenziswa kwe-thionyl chloride kunye ne-sodium methosulfate reactions, i-sodium ethyl sulfate kunye ne-acetic acid reactions, njl.
Ulwazi ngoKhuseleko:
- 3-(Methylthio) propionaldehyde inokutsha kumaqondo obushushu aphezulu kunye namadangatye avulekileyo, kunye neegesi eziyityhefu zinokuveliswa xa zisesichengeni samadangatye avulekileyo.
- Yikhompawundi ecaphukisayo enokubangela ukucaphuka kwamehlo, ulusu, kunye nenkqubo yokuphefumla.
-Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neziphefumli, iimpahla zamehlo ezikhuselayo kunye neeglavu xa usebenzisa.
- Xa ugcina, kufuneka ugcinwe kwindawo epholileyo, nengena umoya, kude nomlilo kunye ne-oxidants.
- Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa ne-oxidants eqinile, i-acids eqinile kunye ne-alkali enamandla ngexesha lokusebenza ukuphepha ukuphendula okuyingozi.
