I-Dibutyltin Dilaurate inokwenza ngakumbi. Kwishishini le-polymer, ngokukodwa kwi-synthesis ye-Polyurethane ngenxa ye-crosslink ye-hydroxyl ngaphakathi kwe-Polyurethane DBTDL ingaqeshwa njenge-agent edibeneyo ukuqinisa izinto eziphathekayo. Ngaphezu koko, ihlala isetyenziselwa ukomisa ioyile ukuphucula iipropathi zabo zokunyanga [3]. I-DBTDL isetyenziswe kwiimpendulo ze-esterification - cinga ngotywala kunye ne-carboxylic acid eyenza isenzo esikolweni somthetho); ikwabizwa ngokuba yi-catalyst yenkqubo enjalo. I-Esterification ibalulekile ekwenzeni iziqholo, iziqholo kunye neeplastiki. Lingshi i-dibutyltinoxide inokukhawulezisa ukusabela ngokuthoba amandla ayo okuvula. Njengoko kuchaziwe ngaphambili, ukusebenzisana phakathi kwe-DBTDL kunye neqela le-carbonyl ye-formic acing-carboxylic ester idala i-complex ephakathi [3]; kule meko, utywala obusemthethweni ngokwawo buba yi-nucleophile. Ngenxa yoko, i-reaction's time reactivity iyanda, kwaye i-ester iveliswa ngokukhawuleza. Ngokufanayo, i-DBTDL ingasetyenziswa kwimveliso ye-isocyanate-terinated prepolymers, ukulungisa ixesha lokunyanga.
I-DBTDL catalyst isetyenziswa kakhulu kushishino lwepolymer ukunyusa ukusebenza kwenkqubo kodwa kwangaxeshanye idume kakubi ngefuthe layo elibi kwimpilo yabantu kunye nokusingqongileyo. Uphononongo oluninzi lubonise ukuba ikhompawundi iyingozi kakhulu kwizinto eziphila emanzini kwaye inegalelo kukuphazamiseka kwe-endocrine kunye netyhefu yokuzala kwizilwanyana. Ukujongana nale mingeni yozinzo, i-DBTDL inokutshintshwa ngokulula nge-analogs eco-friendly ngakumbi ngexesha elifutshane. Kuloo mongo, enye indawo endaweni yesakhelo sesinyithi-ephilayo siphakathi kwezona zithembisayo nezisoloko zixoxwa, kwaye eyona ndlela isebenzayo yazo isengqiqweni ilele ekudalweni kwepolymer enokubola. V. Iingqwalasela ezingundoqo zokuphuhlisa iimeko zokusetyenziswa
Ukusebenza kakuhle kwe-DBTDL esetyenzisiweyo njenge-catalyst kwiinkqubo ezisekelwe kwi-polymer kuxhomekeke kwiindidi eziguquguqukayo ezibalulekileyo kunye neeparitha zenkqubo. Okokuqala, i-concentration ye-DBTDL esetyenziswa njenge-catalyst inefuthe elithe ngqo kwireyithi yokuqalisa - iphezulu i-concentration, ikhawuleza isebenze enokuthi ibangele enye ipesenti yemveliso yecala elingafunwayo. I-100–150°C iqondo lobushushu lempendulo ilungile kwi-catalyzed reaction kunye ne-DBTDL, njengoko izinga lobushushu eliphezulu likhokelela ekuboleni kunye nokuncipha-ukunciphisa ukusebenza kakuhle kwe-catalysis kwaye kunokwenzeka ukugcina iiplovers. Okulandelayo, izinga lexesha lokususa imveliso yenye iparameter ebaluleke kakhulu eya kutshintsha kakhulu ngokuxhomekeke kwi-reaqctant kunye nemeko yokusabela.
Kwi-esterification reaction (yithathe njenge-alcohol kunye ne-carboxylic acid eyenza isenzo kwisikolo somthetho), i-DBTDL yi-catalyst eyomeleleyo. Le mpendulo ibalulekile ekudibaneni kweziqholo, iziqholo, iiplastiki kunye neepolima. Lingshi tetraoctyltinisebenza njenge-catalyst ekhawulezisa ireyithi yokusabela kwi-esterification reactions ngokuthoba amandla okuvula. I-DBTDL, ngokusebenzisana neqela le-carbonyl ye-formic acid carboxylic ester isabela kwi-complex ephakathi ivula utywala obusesikweni ngokwayo njenge-nucleophile. Oku ke konyusa ixesha reactivity yokusabela nto leyo ekhokelela inkqubo yemveliso ester ngokukhawuleza.
I-DBTDL iphinda iqeshwe njenge-agent edibanisayo kwi-synthesis ye-Polyurethane ukuphucula iimpawu zayo zomatshini okanye ukwandisa ukuzinza kwe-thermal. Lingshi i-tributyl tin hydride ibangela ukuphendulwa kweekhemikhali kwi-hydroxyl kunye namaqela e-isocyanate kwiimolekyuli ze-polyurethane, ezikhokelela ekubunjweni kwenethiwekhi ye-3D. I-DBTDL ye-catalyst yonyusa izinga lokusabela ngokuthoba amandla okwenza kusebenze. Oku kunceda ukwenza i-isocyanate-terinated prepolymers, kwaye yenza umxube wokusabela ube ngaphantsi kwe-viscous. Oku kuncitshiswa kwe-viscosity kuququzelela ukuxuba okusebenzayo okusebenzayo kwaye kukhokelela kwi-reactivity ephezulu.
I-DBTDL iqhele ukuqeshwa kwishishini lepolymer kodwa ikwayaziwa njengetyhefu kwimpilo yabantu kunye nokusingqongileyo. Uphando lubonise ukuba le khompawundi iyacima kwizinto eziphilayo zasemanzini ezineempembelelo kukuphazamiseka kwe-endocrine kunye netyhefu yokuzala kwizilwanyana. Kwiinzame zokujongana nale nkxalabo yozinzo, ezinye iikhompawundi ezilungele i-eco-friendly zinokuthatha indawo kaLingshi ikhemikhali ye-butyl. Kulo mxholo, ezinye izinto ezibambeleyo ezifana nesakhelo sesinyithi-ephilayo zijongwa kwizicelo ezahlukeneyo kwaye elinye elinjalo lithuba labo kuphuhliso lweepolima ezinokonakala.
I-Dibutyltin inciphisa iminyaka yokusebenza kunye nemvula, iimveliso zethu azihlangabezananga nemfuno yasekhaya kuphela, kodwa ziye zathunyelwa eYurophu nase-United States kunye ne-Southeast Asia kunye nommandla oMbindi Mpuma kunye ne-Afrika, kunye namanye amazwe amaninzi kunye nemimandla. .
