NPA (ib txwm propyl cawv) hauv chemistry
N-Propyl Alcohol normal propanol (tseem hu ua n-propanol, 1-propanol, Propan-1-l) yog thawj cawv nrog cov mis molecular ntawm CH3 (CH2) 2OH. Nws yog xim tsis muaj xim, pob tshab kua uas muaj cov ntxhiab tsw tsw ntxhiab uas zoo sib xws nrog cov ntxhiab tsw ntawm cov cawv.
Physical Properties of NPA (ib txwm propyl cawv)
Lub cev muaj zog ntawmNPA cawvsuav nrog nws cov boiling point, melting point, thiab ceev. n-Propanol muaj qhov kub ntawm kwv yees li 97℃thiab melting point ntawm -127℃. Nws qhov ceev yog me ntsis tsawg dua dej, ntawm 0.804 g / mL (ntawm 20 degree). Tsis tas li ntawd, n-propanol yog miscible nrog dej hauv txhua qhov kev faib ua feem thiab yooj yim soluble hauv cawv, ethers, thiab ntau lwm cov kuab tshuaj organic.
Chemical Properties of NPA (ib txwm propyl cawv)
NPA cawv yog ib hom cawv sib xyaw ua ke thiab nthuav tawm cov khoom ntawm cawv. Piv txwv li, nws tuaj yeem raug esterification cov tshuaj tiv thaiv nrog acids los tsim cov ester sib txuas. Tsis tas li ntawd, n-propanol tuaj yeem raug oxidation thiab dehydrogenation cov tshuaj tiv thaiv. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias n-propanol muaj qee yam tshuaj lom thiab ua rau khaus tawv nqaij thiab qhov muag; Yog li ntawd, kev tiv thaiv yuav tsum tau ua thaum tuav nws.
Yam ntxwv kev nyab xeeb
NPA (ib txwm propyl cawv) yog cov kua nplaum uas muaj qhov nruab nrab flash point ntawm kwv yees li 15 degree. Nws yog heev flammable thiab nquag combustion thiab tawg thaum sib cuag nrog qhib nplaim taws los yog kub kub. Khaws cia deb ntawm qhov chaw sov thiab hauv qhov dej - qhov cua, qhov chaw qhuav. Kev sib cuag ntawm daim tawv nqaij yuav ua rau mob me me; rau kev tuav ntev, nws raug nquahu kom hnav hnab looj tes tiv thaiv thiab tsom iav thiab tsis txhob nqus pa.
