| Zizindikiro Zowopsa | R22 - Zowopsa ngati zitamezedwa R34 - Imayambitsa kuyaka R36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. |
| Kufotokozera Zachitetezo | S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S36/37/39 - Valani zovala zodzitchinjiriza zoyenera, magolovesi ndi chitetezo chamaso / kumaso. S45 - Pakachitika ngozi kapena ngati simukumva bwino, funsani upangiri wachipatala nthawi yomweyo (onetsani chizindikirocho ngati kuli kotheka.) S36 - Valani zovala zoyenera zodzitetezera. |

Mawu Oyamba
R-(+) tetrahydrofuranoic acid. Zotsatirazi ndizofotokozera zina mwazinthu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha R-(+)tetrahydrofuranoic acid:
Ubwino:
- R-(+) tetrahydrofuranoic acid ndi yolimba yachikasu mpaka yotumbululuka yokhala ndi kukoma kwapadera kowawasa.
- Imasungunuka m'madzi ndipo imawoneka ngati madzi okhala ndi mawonekedwe ozungulira kutentha.
- Imatha kuchita ndi zinthu zina monga esterification, condensation, kuchepetsa, etc.
Gwiritsani ntchito:
- R-(+)tetrahydrofuranoic acid imagwiritsidwanso ntchito popanga zinthu zina zakuthupi, mwachitsanzo popanga mapulasitiki owonongeka monga polylactic acid.
Njira:
- R-(+) tetrahydrofuranoic acid ikhoza kukonzedwa ndi njira zosiyanasiyana monga kupatukana kwa kuwala, kuchepetsa mankhwala, ndi njira za enzymatic.
- Kupatukana kwa kuwala ndi njira yomwe imagwiritsidwa ntchito nthawi zambiri yokonzekera kuti musiyanitse ma isomers ena a D-lactate posankha tizilombo tating'onoting'ono kapena ma enzymes.
Zambiri Zachitetezo:
- R-(+) tetrahydrofuranoic acid ndi yotetezeka pakagwiritsidwe ntchito bwino.
- Kulumikizana kwanthawi yayitali kumatha kuyambitsa kuyabwa pakhungu ndi maso, ndipo kusamala kuyenera kuchitidwa pogwira.
- Posunga ndi kusamalira, njira zoyendetsera chitetezo ziyenera kutsatiridwa mosamalitsa, ndipo kukhudzana ndi ma oxidizing amphamvu ndi zida zoyaka moto ziyenera kupewedwa.
