Isicelo Somkhiqizo

I-EDMingasetshenziswa ikakhulukazi njengesithako se-nitrocellulose, i-resin yokwenziwa, upende kanye noyinki wokunyathelisa. Ingasetshenziswa njengesithako sokususa upende kanye nesincibilikisi ngenxa yokuncibilika kwayo okuhle kakhulu. Ingasetshenziswa futhi njengesithako se-inertia sokwenziwa esingokwemvelo ngenxa yokuqina kwayo kwamakhemikhali.
Ngaphandle kokusetshenziswa okukhulunywe ngakho ngenhla,I-DEDMingasetshenziswa njengesithako sopende oncibilika emanzini, i-ejenti yokulinganisa yesikhumba nefayibha, i-ejenti yokulinganisa esithombeni noma ekuphrinteni, kanye ne-aprotic polar solvent esetshenziswa ekwakhiweni kwezinto eziphilayo.

I-TRIEDMingasetshenziswa ekusabeleni kokwenziwa kwezinto eziphilayo njengesinyibilikisi samaphuzu abilayo aphezulu. Ingasetshenziswa futhi njenge-ejenti yokususa i-sulphurizate noma i-ejenti yokususa i-carbon ye-ammonia yokwenziwa noma igesi yemvelo.

I-TETREDMingasetshenziswa njengesinyibilikisi esihle kakhulu se-alkaline metal hydride futhi isetshenziswe ekuhlanganisweni kwe-alkyl noma ekusetshenzisweni kabusha kwe-chemical reaction. Nge-Louise Alkalinity, ingakwazi ukumunca igesi ye-asidi ngokukhetha ukuze ihlanze igesi yokwenziwa, igesi yemvelo kanye ne-acetylene. (QAPHELA: lo mkhiqizo awukwazi ukudalulwa ngaphandle isikhathi eside, ngaphandle kwalokho ungakhiqiza i-peroxide.)
