N-Methylacetamide, Dimethyl Carbonate, ndi adipic dihydrazide ndi mankhwala ofunikira ndi mapulogalamu osiyanasiyana m'mafakitale osiyanasiyana. Malo awo apadera amawapangitsa kukhala oyenera, mafiyufu, ndi zapakatikati pazachilengedwe. Kumvetsetsa komwe katunduyo, Njira Zopangira, ndipo kugwiritsa ntchito mankhwalawa ndikofunikira kuti mutseke njira zopangira mafakitale ndikupanga kugwiritsa ntchito zatsopano komanso zatsopano.
N-Methylacetamide (Nma):
Katundu: N-methylartamide ndi China n-fithyelartamide wopanga, ndi fungo lopanda utoto wokhala ndi fungo lofatsa. Imasungunuka m'madzi ndipo ili ndi malo owira 202 ° C. Nma ndi chosungunulira chosinthasintha ndipo chimatha kusungunula zingapo zopangidwa ndi zinthu zosiyanasiyana.
Kupanga: N-methyercetamide makamaka amapangidwa ndi zomwe methylamine ndi acetic nohydride. Zomwe zimachitika zimachitika pamaso pa chothandizira, monga pyridine kapena sulfuric acid.
Ntchito: N-methylacereamide imagwiritsidwa ntchito ngati zosungunulira mu mankhwala, malembo, ndi makampani ojambulidwa. Amagwiritsidwanso ntchito ngati pulpizer ndi batchi mu mapangidwe osiyanasiyana.
Dimethyl Carbonate (Dmc):
Katundu: Dimethyl carbonate kuchokera China dimethyl carbonate othandizira, ndi fungo lopanda utoto ndi fungo labwino. Imasungunuka m'madzi ndipo ili ndi malo owiritsa 90 ° C. DMC ndi por aprotic solvent ndipo imatha kusungunula mitundu yosiyanasiyana.
Kupanga: Dimethyl Carbonate imapangidwa ndi zomwe methanol ndi phosgene. Zomwe zimachitika zimachitika pamaso pa chothandizira, monga trielylamine kapena pyridine.
Ntchito: Carbonate ya Dimethyl imagwiritsidwa ntchito ngati solventical, choongoletsera cha zinthu, ndi makampani ojambulidwa. Amagwiritsidwanso ntchito ngati othandizira a methylaing komanso osinthika osokoneza bongo.
Adipic Dihydrazide (ADH):
Katundu: Adipic dihydrazide kudutsa China adipic diihdrazide othandizira, ndi yoyera yoyera. Imasungunuka m'madzi ndipo ili ndi malo osungunuka 129-131 ° C. Adh ndi dihydrazide, kutanthauza kuti muli ndi magulu awiri a hydrazide.
Kupanga: Adipric Dihydrazide imapangidwa ndi zomwe adipric acid ndi hydrazine. Zomwe zimachitika zimachitika pamaso pa chothandizira, monga sodium hydroxide kapena potaziyamu hydroxide.
Ntchito: Adipric dihhydrazide imagwiritsidwa ntchito ngati wothandizila pophulika popanga pulasitiki yopukutira. Amagwiritsidwanso ntchito ngati wothandizila ku Epoxy amayendera ndipo ngati wothandizila ku polyurethane amalizi.
