1,3-dimethylurea CAS:96-31-1

Sebopeho se feto-fetohang sa 1,3-dimethylurea se nolofatsa ts'ebeliso ea eona masimong a fapaneng, ho kenyeletsoa tlhahiso ea lintho tse phelang, lits'ebetso tsa indasteri le saense ea lintho tse bonahalang, se bonts'a bohlokoa ba eona e le ntho ea bohlokoa lipatlisisong tsa lik'hemik'hale le nts'etsopele. Ho qaptjoeng ha lintho tse phelang, 1,3-dimethylurea e sebetsa e le sebaka sa bohlokoa bakeng sa ho lokisa meriana, lik'hemik'hale tsa temo le lik'hemik'hale tse ikhethang. Ho sebetsa ha eona ho lumella ho kenngoa ha lihlopha tse sebetsang le li-motif tsa sebopeho ka har'a limolek'hule tsa lintho tse phelang, ho nolofalletsa ho kopanngoa ha metsoako e fapaneng e nang le thepa e etselitsoeng eona. Ho phaella moo, 1,3-dimethylurea e nka karolo liketsong tsa condensation 'me e sebetsa e le selelekela sa tlhahiso ea metsoako e sebetsang ka baeloji, e totobatsang bohlokoa ba eona ho sibolloeng ha lithethefatsi le tlhahisong ea lik'hemik'hale. Ho feta moo, 1,3-dimethylurea e fumana thuso lefapheng la k'hemistri ea khokahano ea tšepe le catalysis, moo e sebetsang e le ligand ho qaptjoeng ha metsoako ea khokahano le metsoako ea organometallic. Thepa ea eona ea chelating le boitšoaro ba khokahano li etsa hore e lokele ho nolofatsa liketso tse fapaneng tse tsamaisoang ke tšepe, ho kenyeletsoa ho kopana ha metsoako, hydrogenation, le catalysis e sa lekanang. Ka ho sebetsa e le ligand e tšehetsang, 1,3-dimethylurea e kenya letsoho ntlafatsong ea litsamaiso tse ncha tsa catalytic le ho kopanngoa ha thepa e nang le tšepe e nang le lits'ebetso tse fapaneng liphetohong tsa lik'hemik'hale le lits'ebetsong tsa indasteri. Ho feta moo, karolo ea 1,3-dimethylurea e atolohela k'hemistri ea polymer le saense ea thepa, moo e sebetsang e le monomer kapa moemeli oa ho hokahanya ho kopanngoa ha thepa ea polymeric, li-resin le liphahlo. Ho kenyelletsoa ha eona ho li-matrices tsa polymer ho nolofalletsa tlhahiso ea li-polymer tse khethehileng tse nang le thepa e ntlafalitsoeng, joalo ka ho khomarela, botsitso ba mocheso le matla a mechini. Ts'ebeliso ena e sebetsana le tlhoko ea thepa e tsoetseng pele e sebelisoang makaleng a fapaneng a indasteri, ho kenyeletsoa likhomaretsi, li-sealant le liphahlo tse sebetsang hantle. Ho feta moo, 1,3-dimethylurea e sebelisoa lipatlisisong tsa thuto le tsa indasteri bakeng sa ho batlisisa mekhoa ea karabelo, ho nts'etsapele litsela tse ncha tsa maiketsetso, le ho hlahloba lits'ebetso tse ncha tsa lik'hemik'hale. Ho tenyetseha ha eona le thuso ea eona ea maiketsetso li totobatsa bohlokoa ba eona ho ntšetseng pele tsebo ea saense, ho atolosa meeli ea k'hemistri ea lintho tse phelang, le ho sebetsana le litlhoko tse ntseng li fetoha tsa liindasteri tse fapaneng. Ka kakaretso, ts'ebeliso e nang le mahlakore a mangata ea 1,3-dimethylurea e totobatsa bohlokoa ba eona e le motsoako o feto-fetohang o nang le lits'ebetso tse pharaletseng ho tsoakoeng ha lintho tse phelang, ho hlohlelletsa le saense ea lintho tse bonahalang, e totobatsa karolo ea eona e le karolo ea motheo ho tsamaiseng boqapi ba lik'hemik'hale le tsoelo-pele ea indasteri.
