Ingcaciso yeMveliso:
Iasidi yeBarbituric yikhompawundi ephilayo ekwimo yomgubo wekristale emhlophe, inyibilika ngokulula emanzini ashushu kwaye ixutywe neeasidi, inyibilika kwi-ether kwaye inyibilika kancinane emanzini abandayo.Isisombululo esinamanzi sineasidi kakhulu.Inokusabela ngesinyithi ukwenza iityuwa.
Isicelo:
(1) I-Intermediates yokwenziwa kwe-barbiturates, i-phenobarbital kunye ne-vitamin B12, ekwasetyenziswa njenge-catalyst ye-polymerisation kunye ne-raw material yokuveliswa kwedayi.
2
(3) Izinto ezininzi eziphuma kwi-malondiylurea ezineathom ze-hydrogen ezimbini kwiqela le-methylene endaweni yamaqela e-hydrocarbon ziyaziwa ngokuba yi-barbiturates, iklasi ebalulekileyo ye-sedative-hypnotic drug.
