Cov lus qhia:

Kev nruab nrab ntawm cov organic sib txuas thiab cov tshuaj synthes, uas tuaj yeem siv rau cov xaum hluav taws xob ntawm Xike barbital, dyestuff thiab naj hoom, thiab siv los ua av fumigant hauv kev ua liaj ua teb. Lawv kuj tseem siv los ua intermediates rau kev hloov kho resin thiab tsw qab, tshuaj lom neeg hauv tsev, emulsion hloov tshuaj lom neeg, cov khoom siv silicon, thiab lwm yam Nws tau tshaj tawm tias cov polymer, uas tuaj yeem ua polymerize nrog plasma tsim rov qab osmosis ciab, tuaj yeem siv rau hauv airtight manned spaceship, thiab tseem tuaj yeem siv ua kev txhim kho corrosion, catalyst thiab hnyav.

Txoj kev cia khoom ： Khaws rau hauv cov tsev khaws khoom txias thiab cua. Cia kom deb ntawm hluav taws thiab qhov kub. Qhov chaw cia khoom kub yuav tsum tsis pub tshaj 37 ℃. Lub pob yuav tsum muab ntim thiab tsis nyob nrog huab cua. Nws yuav tsum muab khaws cia cais tawm los ntawm oxidant thiab alkali, thiab zam kev sib xyaw cia. Nws yuav tsum tsis txhob cia nyob ntev ntev kom tsis txhob ua kom puas. Kev pov thawj tawg lub teeb pom kev zoo thiab cov chaw dim pa tau saws. Nws yog txwv tsis pub siv cov cuab yeej thiab cov cuab yeej yooj yim los ua cov txim taws. Qhov chaw ntim khoom yuav tsum muaj cov cuab yeej siv kho mob lub sij hawm tiv thaiv kev kub ntxhov thiab cov khoom lag luam kom zoo.

Cov txheej txheem hluavtaws ： Bromination ntawm allyl cawv: hydrobromic acid tau tso rau hauv lub tank cov tshuaj tiv thaiv, sulfuric acid thiab allyl cawv ntxiv rau hauv qab nplawm. Tom qab refluxing rau 2 teev, lub distillate yog evaporated thaum rhuab mus rau 8 ℃, thiab 68-73 raction feem tau khaws. Tom qab ntxuav nrog dej, dehydrate nrog anhydrous sodium sulfate thiab lim kom tau allyl bromide.

Bromination ntawm propylene.

Kev haus dej cawv hauv tsev yog ib qho tseem ceeb heev hauv nruab nrab ntawm cov organic synthesis. Lub ntsiab hluavtaws tseem ceeb yog kev sib txuas ntxiv ntawm allyl hlau reagents thiab carbonyl compound. Cov khoom siv hlau uas nquag siv nrog allyl lithium (Mg, Zn, B, hauv, Si, Sn, Ti), thiab lwm yam, Yog li peb siv Grignard reagent ntawm allyl los coj los ua ke
