Tsis tas li ntawd xwb,dibutyltin dilauratesiv ua tus catalyst hauv kev tsim cov polyester resins. Los ntawm kev txhawb nqa cov tshuaj esterification thiab transesterification, DBTDL pab txhawb kev tsim cov ntaub ntawv polyester siv hauv kev tsim cov ntaub, ntim khoom, thiab ntau yam kev siv hauv kev lag luam. Nws lub luag haujlwm catalytic hauv cov txheej txheem no pab txhawb rau kev txhim kho cov khoom zoo thiab kev ua kom zoo dua ntawm kev tsim khoom.
Ntxiv rau nws lub luag haujlwm hauv polymerization thiab esterification, dibutyltin dilaurate yog siv rau hauv kev tsim cov silicone elastomers thiab sealants. Lub catalytic activity ntawm DBTDL yog qhov tseem ceeb hauv kev sib txuas ntawm cov silicone polymers, ua rau muaj cov ntaub ntawv elastomeric nrog cov khoom siv kho tshuab zoo heev thiab tiv taus cua sov thiab tshuaj lom neeg. Ntxiv mus, dibutyltin dilaurate ua haujlwm ua tus catalyst hauv kev kho cov silicone sealants, ua rau muaj kev tsim cov khoom siv sealant ruaj khov thiab tiv taus huab cua uas siv dav hauv kev tsim kho thiab kev siv tsheb.
Qhov ua tau ntau yam ntawm dibutyltin dilaurate nthuav dav mus rau nws daim ntawv thov ua tus catalyst hauv kev tsim cov tshuaj intermediates thiab cov tshuaj zoo. Nws cov khoom catalytic ua lub luag haujlwm tseem ceeb hauv kev pab txhawb ntau yam kev hloov pauv organic, suav nrog acylation, alkylation, thiab condensation reactions, uas yog cov kauj ruam tseem ceeb hauv kev tsim cov tshuaj sib xyaw thiab cov tshuaj tshwj xeeb. Kev siv DBTDL ua tus catalyst hauv cov txheej txheem no pab txhawb rau kev tsim cov khoom siv tshuaj muaj nqis nrog ntau yam kev siv.
Txawm hais tias nws siv dav dav ua tus catalyst,dibutyltin dilauratetau tsa kev txhawj xeeb txog nws cov kev cuam tshuam rau ib puag ncig thiab kev noj qab haus huv. Raws li ib qho organotin compound, DBTDL tau raug tshuaj xyuas los ntawm kev tswj hwm vim nws qhov lom thiab kev nyob ntev hauv ib puag ncig. Kev siv zog tau ua los txo qhov cuam tshuam rau ib puag ncig ntawm dibutyltin dilaurate los ntawm kev tsim cov tshuaj catalysts lwm txoj hauv kev thiab kev siv cov cai nruj tswj hwm nws siv thiab pov tseg.
Xaus lus, dibutyltin dilaurate yog ib qho tshuaj catalyst muaj txiaj ntsig zoo nrog ntau yam kev siv hauv kev lag luam tshuaj lom neeg. Nws lub luag haujlwm hauv polymerization, esterification, silicone synthesis, thiab organic transformations qhia txog nws qhov tseem ceeb hauv kev tsim ntau yam khoom lag luam thiab cov khoom siv. Txawm hais tias nws cov khoom catalytic yog cov cuab yeej tseem ceeb hauv kev tsav tsheb ntau yam txheej txheem tshuaj lom neeg, kev siv thiab kev tswj hwm ntawm dibutyltin dilaurate yog qhov tseem ceeb los txo cov kev pheej hmoo ib puag ncig thiab kev noj qab haus huv cuam tshuam nrog nws siv. Raws li kev tshawb fawb thiab kev tsim kho tshiab txuas ntxiv mus, kev tsim cov tshuaj catalysts ruaj khov thiab muaj kev nyab xeeb dua yuav pab txhawb rau kev hloov pauv ntawm kev lag luam tshuaj mus rau kev coj ua zoo dua rau ib puag ncig.
