Nhanganyaya
R-(+) tetrahydrofuranoic acid. Izvi zvinotevera sumo kune zvimwe zvezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza R-(+)tetrahydrofuranoic acid:
Hunhu:
- R-(+)tetrahydrofuranoic asidhi haina ruvara kune yakachenuruka yero yakasimba uye inovavira zvakasiyana.
- Inonyungudika mumvura uye inoratidzika semvura ine optical rotation pakamuri tembiricha.
- Inogona kuita nemamwe makomisheni senge esterification, condensation, kuderedza, nezvimwe.
Shandisa:
- R-(+)tetrahydrofuranoic acid inoshandiswawo mukugadzirwa kwemamwe organic compounds, eg mukugadzirwa kwebiodegradable plastics yakadai sepolylactic acid.
Nzira:
- R-(+) tetrahydrofuranoic acid inogona kugadzirirwa nenzira dzakasiyana-siyana dzakadai sekuparadzaniswa kwemaziso, kuderedza kemikari, uye nzira dze enzymatic.
- Optical separation inzira inowanzoshandiswa yekugadzirira kuparadzanisa mamwe maisomers eD-lactate nekusarudza akakodzera ma microorganisms kana enzymes.
Zvekuchengetedza
- R-(+)tetrahydrofuranoic acid yakachengeteka pasi pemamiriro ekushandiswa akajairwa.
-Kubata kwenguva refu kunogona kukonzera kushatirwa kweganda nemeso, uye kungwarira kunofanirwa kutorwa pakubata.
- Paunenge uchichengeta uye uchibata, maitiro ekuchengetedza akakodzera anofanirwa kuteedzerwa, uye kusangana neakasimba oxidizing agents uye zvinhu zvinopfuta zvinofanirwa kudziviswa.
