Okwu mmalite
Dimethoxyaniline (N-methylaniline) bụ ngwakọta organic. Ọ bụ amine organic nwere ụdị mmanya-amine yana pKa nke ihe dịka 4.64. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke dimethoxyaniline:
Ogo:
- Ọdịdị: Dimethoxyaniline bụ mmiri mmiri na-acha odo odo na-enweghị agba.
- Solubility: Enwere ike ịgbaze ya n'ọtụtụ ihe mgbaze organic, dị ka alcohols, ethers, na chlorinated hydrocarbons.
- Nsi: Ọ bụ ihe na-egbu egbu, na ikpughe ma ọ bụ iku ume nke nnukwu vapors ma ọ bụ mmiri mmiri nwere ike imerụ ahụ ike.
