Solubility

Yooj yim soluble hauv dej thiab cov kuab tshuaj uas muaj halogenated hydrocarbons, cawv, amines, nitroalkanes thiab tsis tshua muaj molecular fatty acids, thiab lwm yam, tab sis insoluble nyob rau hauv ob peb cov kuab tshuaj xws li acetone, ether, turpentine, aliphatic hydrocarbons thiab alicyclic hydrocarbons. Tau tshaj feem ntau inorganic ntsev thiab ntau yam resins.

Crosslinked homopolymer ntawm ntshiab vinylpyrrolidone. Nws muaj peev xwm ntawm polyvinylpyrrolidone (PVP) kom complex nrog ntau yam tshuaj (xws li ntau yam glutinous tshuaj uas ua rau lub discoloration ntawm dej haus xws li caw). Thiab vim nws insolubility, nws yog ib qho yooj yim mus tshem tawm tom qab pom.

Daim ntawv thov:

Los ntawm kev pom kev lom neeg, cov yam ntxwv ntawm PVP molecule zoo ib yam li cov qauv siv cov protein yooj yim, thiab txawm tias nws cov kua dej muaj peev xwm los koom tes nrog qee cov molecules me me thiab tuaj yeem siv los ntawm qee cov protein precipitants, ammonium sulfate thiab nag lossis daus. Cov khoom ntawm chloroacetic acid, tannic acid thiab phenols kuj sib xws nrog cov proteins. Ntawm lawv PVPK30 tau raug teev npe nyob rau hauv kev ua lag luam nrog kev pom zoo los ntawm lub chaw saib xyuas tshuaj. Lub tuam txhab tseem muab povidone K30 nrog tus lej pom zoo.
