1,8-Diazabicyclo[5.4.0]undec-7-ene CAS 6674-22-2 Daim ntawv thov

Cov khoom no yog ib qho catalyst siv nyob rau hauv zus tau tej cov polyurethane thiab lwm yam tshuaj, xws li ammonia thiab dichloroethane react nyob rau hauv nws muaj los tsim piperazine. Nws yog ib qho zoo heev dehydrating tus neeg saib xyuas, epoxy resin hardener, xeb inhibitor, thiab tseem tuaj yeem siv los npaj cov tshuaj tiv thaiv corrosion siab heev. Tam sim no, nws yog dav siv nyob rau hauv zus tau tej cov cephalosporin semi hluavtaws tshuaj tua kab mob. Nws kuj yog siv nyob rau hauv cov organic synthetic tshua thiab semi-synthetic tshuaj tua kab mob.

Siv 1, 8-diazabicycloundecano-7-ene (DBU) tuaj yeem siv los ua ib qho khoom siv rau kev tsim cov polyurethane thiab lwm yam tshuaj, xws li ammonia thiab dichloroethane react nyob rau hauv nws lub xub ntiag los tsim piperazine. Nws yog ib qho zoo heev dehydrating tus neeg saib xyuas, epoxy resin hardener, xeb inhibitor, thiab yuav siv tau los npaj siab corrosion inhibitor.

Nws yog dav siv nyob rau hauv zus tau tej cov cephalosporin semi synthetic tshuaj tua kab mob. Resin curing accelerator, tshwj xeeb tshaj yog rau cov txheej txheem sealing ntawm kev sib xyaw ua ke thiab cov khoom siv hluav taws xob; Cov tshuaj tiv thaiv dehalogenation, dimerization thiab trimer dehalogenation cov tshuaj tiv thaiv; Desulfonic acid thiab nitric acid cov tshuaj tiv thaiv nyob rau hauv cov txheej txheem polymerization.

Siv: amidine puag rau dehydrogenation thiab halogenation cov tshuaj tiv thaiv los tsim olefins; Cov ntawv thov tseem ceeb dua yog: esterification ntawm carboxylic acids nrog alkyl halides; Lub alkylation thiab acylation ntawm active methylene tebchaw yog siv nyob rau hauv lub tsim ntawm cephalosporin semi hluavtaws tshuaj tua kab mob, nrog rau kev npaj ntawm deacidifying agents, xeb inhibitors, advanced corrosion inhibitors, thiab lwm yam.
