(R)-tetrahydrofuran-2-carboxylic acid (CAS#87392-05-0)
| Iikhowudi zoMngcipheko | I-R22 – Iyingozi xa iginyiwe I-R34 – Ibangela ukutsha R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. |
| Inkcazelo yoKhuseleko | S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. 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.) S36 – Nxiba iimpahla ezifanelekileyo ezikhuselayo. |

Intshayelelo
R-(+) tetrahydrofuranoic acid. Oku kulandelayo kukwaziswa kwezinye iipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-R-(+) tetrahydrofuranoic acid:
Umgangatho:
- R-(+)tetrahydrofuranoic acid ayinabala ukuya kumthubi okuqinileyo kunye nencasa emuncu engaqhelekanga.
- Iyanyibilika emanzini kwaye ibonakala njengolwelo kunye nokujikeleza kwe-optical kwiqondo lokushisa.
- Inokusabela kunye nezinye iikhompawundi ezifana ne-esterification, ukudibanisa, ukunciphisa, njl.
Sebenzisa:
I-R-(+) i-tetrahydrofuranoic acid ikwasetyenziswa ekulungiseni ezinye iikhompawundi ze-organic, umz. ekudityanisweni kweeplastiki ezinokubola njenge-polylactic acid.
Indlela:
- I-R-(+) i-tetrahydrofuranoic acid inokulungiswa ngeendlela ezahlukeneyo ezifana nokuhlukana kwe-optical, ukunciphisa imichiza, kunye neendlela ze-enzymatic.
- Ukwahlula kwamehlo yindlela esetyenziswa ngokuqhelekileyo yokulungiselela ukwahlula ezinye ii-isomer ze-D-lactate ngokukhetha ii-microorganisms ezifanelekileyo okanye i-enzymes.
Ulwazi ngoKhuseleko:
- I-R-(+) i-tetrahydrofuranoic acid ikhuselekile ngokufanelekileyo phantsi kweemeko eziqhelekileyo zokusetyenziswa.
- Ukudibana kwexesha elide kunokubangela ukucaphuka kwesikhumba kunye namehlo, kwaye kufuneka kuthathwe amanyathelo okhuseleko xa uphathwa.
- Xa ugcina kunye nokuphatha, iinkqubo ezifanelekileyo zokusebenza zokhuseleko kufuneka zithotyelwe ngokungqongqo, kwaye ukudibanisa nee-oxidizing agents ezinamandla kunye nezinto ezinokutsha kufuneka zigwenywe.
