Indlela Yokusabela

Ukwakheka kweHydrazone Bond

I-ADH isabela kunye namaqela e-ketone okanye e-aldehyde ukuze yenze iibhondi ze-hydrazone nge-condensation reaction, ebonakaliswa yi:

1. Ukususwa kwamanzi njengemveliso engasemva.
2. Ukwakhiwa konxibelelwano oluzinzileyo oludibeneyo.

Umzekelo Wokuphendula:

Le mpendulo ibalulekile ekudaleni izixhobo ezinokumelana okuphezulu noxinzelelo loomatshini, ubushushu, kunye nokusingqongileyo.

Iingenelo zokusebenzisa i-ADH

1. Uzinzo lweeKhemikhali:Iibhondi zeHydrazone ezenziwe yiADH ziyakwazi ukumelana kakhulu nehydrolysis kunye nokuwohloka.
2. Ukumelana nobushushu:Iphucula uzinzo lobushushu bezinto.
3. Ubuthi obuphantsi:Ikhuselekile xa ithelekiswa nezinye iindlela zokudibanisa ii-cross-linkers.
4. Ukuhambelana kwamanzi:Ukunyibilika kwamanzi kwenza ukuba afaneleke kwiifomyula ezisebenzisa amanzi nezinobuhlobo nokusingqongileyo.
5. Ukuguquguquka:Iyahambelana neendidi ezahlukeneyo zeematrices zepolymer kunye namaqela asabelayo.
