Vanillyl butyl ether CAS 82654-98-6 Daim ntawv thov

N-methylpyrrolidone hu ua NMP luv luv, thiab nws cov mis molecular yog c5h9no. Lus Askiv: 1-methyl-2-pyrrolidinone. Nws yog xim tsis muaj xim rau lub teeb daj pob tshab kua nrog me ntsis ammonia tsw. Nws yog miscible nrog dej nyob rau hauv ib qho kev faib ua feem, thiab soluble nyob rau hauv ntau yam organic solvents xws li ether, acetone, esters, halogenated hydrocarbons, aromatics, thiab lwm yam. nws yog yuav luag tag tov nrog tag nrho cov kuab tshuaj nyob rau hauv cov tshuaj. Nws cov ntsiab lus kub kub yog 204 âជន, flash point yog 91 â, thiab nws muaj zog hygroscopicity, ruaj khov khoom, thiab tsis corrosive rau carbon steel thiab txhuas, me ntsis corrosive rau tooj liab. Nws muaj qhov zoo ntawm cov viscosity tsawg, zoo tshuaj thiab thermal stability, siab polarity, tsis tshua muaj volatility, thiab infinite miscibility nrog dej thiab ntau cov organic solvents. Cov khoom no yog cov tshuaj micro, thiab qhov tso cai txwv tsis pub muaj nyob hauv huab cua yog 100ppm.
