    Isicelo

    1.Kuwukunambitheka kokudla, okusetshenziselwa ikakhulukazi ukulungisa ukunambitheka kwezithelo njengamapheya, ama-apula, amagilebhisi nama-cherry.

    I-2.Isetshenziswa kabanzi ekuhlanganiseni kwe-barbituric acid, ama-amino acids, amaVithamini B1, B2 no-B6, izidakamizwa zokulala kanye ne-phenylbutazone.

    I-3.Ibuye isetshenziswe kabanzi kweminye imikhakha yokukhiqiza amakhemikhali, okuhlanganisa izibulala-zinambuzane, odayi bezimboni, izinto zekristalu eziwuketshezi, njll.

    Impahla

    Incibilika ku-chloroform, benzene nezinye izinyibilikisi eziphilayo.Incibilika kancane emanzini.

    Isitoreji

    1. Gcina endaweni epholile, nengena umoya.Gcina kude nomlilo nemithombo yokushisa.Kufanele igcinwe ngokuhlukana nama-oxidants, ama-alkali aqinile, nama-ejenti anciphisayo, futhi igweme ukugcinwa okuxubile.Ifakwe izinhlobonhlobo ezifanele kanye nenani lamathuluzi omlilo.Indawo yokugcina impahla kufanele ifakwe izinto zokwelashwa eziphuthumayo ezivuzayo kanye nezinto ezifanele zokugcina.

    2. Gcina futhi uthuthe ngokuhambisana nemithethonqubo yamakhemikhali avuthayo.

    Ukuzinza

    1. Gwema ukuthintana nama-oxidants, ama-reduction agents nama-alkali.Izakhiwo zamakhemikhali zizinzile kune-diethyl oxalate.Njengoba i-hydrolyzed kalula ukukhiqiza i-malonic acid, ene-acidic eyengeziwe, kuyadingeka ukuvimbela ukuhogela komhwamuko noma ukuthintana nesikhumba.

    2. Lo mkhiqizo unobuthi obuphansi, i-rat oral LD50>1600mg/kg, kodwa izofakwa nge-hydrolyzed ibe yi-asidi emzimbeni, gwema ukuthintana.Geza ngemva kokuxhumana.Abasebenzi kufanele bagqoke amagilavu ​​enjoloba.
