Glycerol ester ntawm ntoo rosin yog tsim los ntawm esterification los ntawm ntoo rosin thiab glycerol. Muaj ob lub txheej txheem kev tsim ua rau kev ua kom huv ntawm cov ntoo rosin ester, nyob ntawm lub hom phiaj ntawm kev siv, ua kom huv los ntawm cov khaub thuas tawm thaum siv hauv cov zom zom, los yog ntxuav los ntawm counter-tam sim no chav npau npau yog siv los kho qhov ntom ntawm cov roj txiv ntoo rau cov dej haus. Cov.
Cov khoom ua los ntawm cov ntoo zoo nkauj tawm los ntawm cov laus thuv thuv, nws tuaj yeem kho kom zoo los ntawm kev tshem tawm cov roj thiab cov nplaim tawg ua ntej cov esterification nrog glycerol.
Cheebtsam
Nws muaj kwv yees li ntawm. 90% resin acids (feem ntau ntawm abietic acid) thiab 10% neutrals (non-acidic compounds).
Ntuj suav daws
Cov rosin ntoo tuaj yeem yog tau los ntawm Pinus palustris (thuv ntev ntawm nplooj ntoo) thiab Pinus Elliottii (luaj ntoo thuv). Nws yog qhov sib txawv nrog cov pos hniav rosin, uas yog ib qho exudate ntawm cov ntoo thuv ntoo, muaj cov khoom sib xws nrog cov pos hniav ntoo; kuj sib txawv nrog cov roj siab hauv rosin, uas yog kev ua haujlwm ntawm kraft (ntawv) pulp processing.
