Okwu mmalite
Acid (acid) bụ ngwakọta organic nwere usoro kemịkalụ C6H4ClNO2.
Ọdịdị:
Acid bụ kristal na-acha ọcha na-acha odo odo siri ike nwere isi pụrụ iche. Ọ bụ soluble na ụfọdụ ihe mgbaze organic, dị ka ethanol, dimethyl sulfoxide na dichloromethane, ma nwere obere solubility na mmiri. Ọ kwụsiri ike na ikuku wee decomposes na oke okpomọkụ.
Jiri:
Acid bụ ihe dị mkpa organic intermediate, nke a na-ejikarị eme ihe na njikọ nke ogige ndị ọzọ. Enwere ike iji ya na nkwadebe nke pesticides, ọgwụ ọjọọ, ihe eji esiji ákwà na ogige nhazi.
Ụzọ nkwadebe:
Enwere ike ịmepụta acid site na ụzọ dị iche iche, usoro a na-ejikarị eme ihe gụnyere abụọ ndị a:
1. 2-picolinic acid chloride na-emeghachi omume na chloroacetic acid iji mepụta ngwaahịa ezubere iche site n'enyemaka nke ihe na-akpata na n'okpuru ọnọdụ kwesịrị ekwesị.
2. meghachi omume 2-pyridyl methanol na carbonic acid chloride, wee mee hydrolyze na acid iji nweta acid.
