Green chemistry enwetala nlebara anya dị ukwuu n'afọ ndị na-adịbeghị anya n'ihi na ọ na-elekwasị anya na omume na-adigide na gburugburu ebe obibi.Otu mpaghara hụrụla nnukwu ọganihu bụ mmepe na itinye n'ọrụ nke ihe ndị na-eme ka mmadụ nwee ike ịkwalite mmeghachi omume enyi na enyi.Tetrabutylammonium iodide (TBAI) apụtala dị ka otu ihe na-akpali akpali, yana akụrụngwa ya pụrụ iche na-eme ka ọ bụrụ ezigbo onye ndoro-ndoro maka ịkwalite mgbanwe kemịkalụ ndụ ndụ.
TBAI, nke nwere nọmba CAS 311-28-4, bụ nnu ammonium nke anọ nke nwere tetraalkylammonium cation na iodide anion.Ọ bụ kristal na-acha ọcha siri ike nke na-agbaze nke ukwuu na ihe mgbaze nkịtị.A mụọla TBAI nke ọma wee jiri ya mee ihe dị ka ihe na-akpali akpali na mmeghachi omume organic dị iche iche, na-egosipụta ịdị irè ya na ngbanwe ya n'ịkwalite kemịkalụ ndụ ndụ.
Otu n'ime uru bụ isi nke iji TBAI bụ ikike ya ime ka ọnụego mmeghachi omume dị ngwa ngwa ma na-ebelata mkpa maka ọnọdụ mmeghachi omume siri ike.Ngwakọta organic omenala na-achọkarị okpomọkụ dị elu na nrụgide, yana iji reagents na-egbu egbu na nke dị ize ndụ.Ọnọdụ ndị a ọ bụghị nanị na-ebute ihe ize ndụ na gburugburu ebe obibi kamakwa na-eduga n'ịmụpụta nnukwu ihe mkpofu.
N'ụzọ dị iche, TBAI na-enyere mmeghachi omume aka ịga n'ihu nke ọma n'ọnọdụ dịtụ nro, na-ebelata oriri ike yana ibelata mmepụta ihe mkpofu.Nke a bara uru karịsịa maka usoro mmepụta ihe, ebe nnabata nke ụkpụrụ kemịkalụ ndụ ndụ nwere ike iduga nnukwu ego nchekwa na uru gburugburu ebe obibi.
