Nhanganyaya
pent-4-ynoic acid, inozivikanwawo se pent-4-ynoic acid, kemikari formula C5H6O2. Iyi inotevera sumo kune hunhu, kushandiswa, kuumbwa uye kuchengetedza ruzivo rwepent-4-ynoic acid:
Zvakasikwa:
- pent-4-ynoic acid imvura isina ruvara uye inonhuwa.
-Iyo hukama hwema molecular mass ndeye 102.1g / mol.
Shandisa:
- pent-4-ynoic asidhi yakakosha yepakati mumakemikari synthesis uye inoshandiswa kugadzira mamwe makomisheni.
-Inogona kushandiswa kuita carbonylation reaction, condensation reaction uye esterification reaction mune organic synthesis reaction.
- pent-4-ynoic acid inogonawo kushandiswa mukugadzirira kwemishonga, zvinonhuwira uye dhayi.
Kugadzirira nzira:
-Kugadzirira kwepent-4-ynoic acid inogona kuwanikwa ne1-chloropentyne uye acid hydrolysis. Kutanga, 1-chloropentyne inobatwa nemvura kuti ipe aldehyde inoenderana kana ketone, uye ipapo aldehyde kana ketone inoshandurwa kuva pent-4-ynoic acid nekuita oxidation.
Zvekuchengetedza
- pent-4-ynoic acid ikemikari inogumbura inogona kukonzera kutsamwa nekuputika mukubatana neganda nemaziso.
-Pfeka magirovhosi ekudzivirira, magirazi, uye zvipfeko zvemurabhoritari paunenge uchishandisa pent-4-ynoic acid.
-Kana ukasangana neganda kana maziso, sukurudza nekukurumidza nemvura yakawanda uye tsvaga kurapwa.
-Dzivisa kusangana neoxidants, yakasimba acids uye mabhesi akasimba panguva yekuchengetedza uye shandisa kudzivirira kuita zvine njodzi.
Ndapota cherechedza kuti usati washandisa chero kemikari, unofanira kuverenga pepa rekuchengetedza data (MSDS) yekemikari zvakanyatsonaka uye uteedzere nzira dzakarurama dzekushanda uye nzira dzakachengeteka dzekushanda.
