Molecular Structure ntawm Cardanol
Cardanol yog cov khoom tseem ceeb ntawm cov kua txiv hmab txiv ntoo, thiab nws lub npe tshuaj yog m-pentadecylphenol. Tus qauv tsim, nws muaj lub nplhaib phenol thiab kaum tsib -carbon alkyl saw. Cov ntsiab lus tseem ceeb yog:
Lub nplhaib phenol txuas nrog cov saw hlau saturated alkyl.
Cov qauv molecular tsis muaj carbon -carbon ob daim ntawv cog lus.
Cov pawg allyl (-CH2-CH=CH2) yog ib pawg uas muaj ob daim ntawv cog lus.
Cov lus xaus yog qhov tseeb: tus qauv cardanol molecule tsis muaj cov qauv allyl.
Vim li cas lo lus nug no tshwm sim
Cov lus nug no yuav tshwm sim los ntawm:
Qhov muaj peev xwm ntawm cov kab derivatives raug tsim thaum lub sij hawm cashew nutshell roj ua.
Allylphenol yog ib qho tshuaj lom neeg nruab nrab.
Qhov zoo sib xws hauv cov npe ntawm cardanol thiab allylphenol tshuaj.
Txawm li cas los xij, nws yuav tsum tau hais qhia tias ntuj cardanol nws tus kheej tsis muaj cov pab pawg allyl.
III. Kev siv tswv yim ntawm Cardanol
Txawm hais tias nws tsis muaj ib pawg allyl, cardanol tseem muaj ntau yam kev siv:
Resin modification: Siv phenolic hydroxyl pawg rau tshuaj lom neeg cov tshuaj tiv thaiv.
Cov ntaub ntawv sib txhuam: Cov ntev - saw alkyl pawg muab lubrication.
Anticorrosive coatings: Cov qauv phenol muaj cov tshuaj tua kab mob.
