Mashandisirwo:
DMA18 inoshandiswa muindasitiri yemakemikari yezuva nezuva kugadzira zvinotonhodza bvudzi, zvinhu zvekugadzira zve anti-static agents, nezvimwewo.

Nzira yekugadzira iyi inosanganisira kuunganidzwa kweoctadecylamine, formaldehyde, uye formic acid. Kutanga, octadecylamine inowedzerwa mu reactor uye inosanganiswa zvakaenzana mu ethanol medium. Formic acid inowedzerwa uku tembiricha ichidzorwa pa50-60℃. Mushure mekukurunga kwemaminitsi akati wandei, formaldehyde inowedzerwa pa60-65℃ (Chemicalbook tembiricha). Tembiricha inokwidzwa kusvika 80-83℃ uye inodzoserwa kwemaawa maviri. Musanganiswa wacho unozobviswa ne liquid alkali kuti pH ipfuure 10. Mushure mekumira nekupatsanurana kuita zvikamu, mvura inobviswa, uye ethanol inobviswa ne vacuum distillation. Mushure mekutonhodza, N,N-dimethyloctadecylamine inowanikwa.
