Taw qhia
Raspberry acetopyruvate yog ib qho organic compound. Nws yog cov kua uas tsis muaj xim nrog lub aroma ntawm fruity.
Nws fruity aroma txhim kho saj thiab tsw ntawm cov khoom. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua ke rau lwm cov organic tebchaw, uas yog ntau yam.
Muaj ob txoj hauv kev los npaj raspberry ketone acetate. Ib tug yog tau los ntawm reacting raspberry ketone ester nrog acetic acid nyob rau hauv lub xub ntiag ntawm ib tug acid catalyst; Lwm qhov yog synthesized los ntawm reacting raspberry ketone nrog acetic anhydride nyob rau hauv lub xub ntiag ntawm alkali catalyst.
Cov ntaub ntawv kev nyab xeeb: Raspberry ketone acetate muaj cov tshuaj toxicity tsawg, tab sis nws tseem yuav tsum tau them sai sai rau kev siv nyab xeeb. Cov iav tiv thaiv tsim nyog yuav tsum tau hnav thaum tuav raspberry ketone acetate los tiv thaiv nws los ntawm kev sib cuag nrog daim tawv nqaij thiab qhov muag. Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav thiab zoo-ventilated kom tsis txhob muaj oxidants thiab ignition qhov chaw.
