(R)-tetrahydrofuran-2-carboxylic acid (CAS#87392-05-0)
| Amakhodi Engozi | I-R22 – Iyingozi uma igwinywe R34 – Ibangela ukusha R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. 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.) S36 – Gqoka izingubo ezifanele zokuzivikela. |

Isingeniso
I-R-(+) i-tetrahydrofuranoic acid. Okulandelayo yisingeniso kwezinye zezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-R-(+)tetrahydrofuranoic acid:
Ikhwalithi:
- I-R-(+) i-tetrahydrofuranoic acid iqinile engenambala ukuya kokuphuzi okuphaphathekile enokunambitheka okumuncu okungavamile.
- Incibilika emanzini futhi ibonakala njengoketshezi oluzungeza ukukhanya ekamelweni lokushisa.
- Ingasabela nezinye izinhlanganisela ezifana ne-esterification, condensation, ukunciphisa, njll.
Sebenzisa:
- I-R-(+) i-tetrahydrofuranoic acid iphinde isetshenziswe ekulungiseni ezinye izinhlanganisela eziphilayo, isb ekuhlanganiseni amapulasitiki abolayo njenge-polylactic acid.
Indlela:
- I-R-(+) i-tetrahydrofuranoic acid ingalungiswa ngezindlela ezihlukahlukene ezifana nokuhlukaniswa kwe-optical, ukunciphisa amakhemikhali, nezindlela ze-enzymatic.
- Ukuhlukaniswa kwamehlo kuyindlela evame ukusetshenziswa yokulungiselela ukuhlukanisa amanye ama-isomer e-D-lactate ngokukhetha ama-microorganisms afanelekile noma ama-enzyme.
Ulwazi Lokuphepha:
- I-R-(+) i-tetrahydrofuranoic acid iphephile uma kuqhathaniswa ngaphansi kwezimo zokusetshenziswa ezijwayelekile.
- Ukuthintana isikhathi eside kungase kubangele ukucasuka esikhumbeni nasemehlweni, futhi kufanele kuthathwe izinyathelo zokuphepha lapho uphathwa.
- Lapho ugcina futhi uphatha, izinqubo ezifanele zokusebenza zokuphepha kufanele zilandelwe ngokuqinile, futhi ukuxhumana nama-oxidizing agents aqinile kanye nezinto ezivuthayo kufanele kugwenywe.
