Taw qhia

Isoamyl salicylate. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm isoamyl salicylate:

Zoo:

Isoamyl salicylate yog cov kua tsis muaj xim uas muaj qhov tshwj xeeb aroma ntawm chav tsev kub. Nws yog volatile, soluble nyob rau hauv cawv thiab ether solvents, thiab insoluble nyob rau hauv dej.

Siv:

Isoamyl salicylate feem ntau yog siv los ua tshuaj tsw qab thiab hnyav.

Txoj kev:

Feem ntau, txoj kev npaj isoamyl salicylate yog ua los ntawm esterification cov tshuaj tiv thaiv. Isoamyl cawv yog reacted nrog salicylic acid nyob rau hauv lub xub ntiag ntawm ib tug acid catalyst los tsim isoamyl alicylate.

Cov ntaub ntawv kev nyab xeeb:

Isoamyl salicylate feem ntau suav hais tias yog ib qho kev nyab xeeb zoo nyob rau hauv kev siv dav dav. Nws tseem yog cov kua hluav taws kub thiab yuav tsum tau tiv thaiv los ntawm kev raug nplaim taws los yog kub kub. Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj kev sib cuag nrog daim tawv nqaij, qhov muag, thiab kab mob ua pa thaum siv isoamyl salicylate.
