| 4-Kev siv Chlorobenzaldehyde Thiab Synthesis |
| Chemical Properties | 4-chlorobenzaldehyde zoo li tsis muaj xim rau lub teeb daj crystalline hmoov. Insoluble hauv dej, yooj yim soluble hauv ethanol, ether, benzene, soluble hauv dej, acetone. Yuav tau volatilized nrog dej vapor. Nws tuaj yeem tsim los ntawm oxidation ntawm 4-chlorobenzyl cawv. 4-chlorobenzaldehyde yog nruab nrab ntawm fungicide tebuconazole thiab cog kev loj hlob regulator uniconazole. |
| Siv | 4-Chlorobenzaldehyde yog siv los ua qhov nruab nrab rau kev tsim cov dyestuffs, optical brighteners, kws tshuaj, tshuaj ua liaj ua teb thiab cov khoom siv hlau. |
| Kev npaj | 4-Chlorobenzaldehyde tuaj yeem tau los ntawm chlorinated hydrolysis ntawm p-chlorotoluene: ntxiv p-chlorotoluene thiab phosphorus trichloride rau lub lauj kaub tshuaj tiv thaiv, nce qhov kub kom txog 155 degree hauv qab lub teeb thiab dhau chlorine. Tswj qhov kub ntawm 160-170 degree thiab hla cov tshuaj chlorine mus rau tus lej suav kom tau txais cov tshuaj chlorination. Ntxiv nws mus rau concentrated sulfuric acid nrog nplawm, thiab do rau 5h ntawm chav tsev kub. Cia nws sawv ntsug thiab stratify, nqa cov txheej qis rau hauv dej khov kom crystallize, thiab lim nws thaum nws txias rau qis dua 5 degree. Lub ncuav mog qab zib lim tau ntxuav nrog dej khov kom tau cov khoom nyoos, distilled nyob rau hauv lub siab txo thiab sau 108-111 degree (3.33kPa) feem kom tau p-chlorobenzaldehyde. |

| Kev piav qhia dav dav | Tsis muaj xim rau daj hmoov los yog dawb crystalline khoom. Tus ntxhiab tsw. |
| Cua & Dej Reactions | 4-Chlorobenzaldehyde yog rhiab heev rau huab cua. Insoluble hauv dej. |
| Reactivity Profile | 4-Chlorobenzaldehyde yog rhiab heev rau huab cua. 4-Chlorobenzaldehyde kuj rhiab rau lub teeb. REACTIVITY: 4-Chlorobenzaldehyde tsis sib haum nrog cov hauv paus muaj zog, muaj zog oxidizers thiab muaj zog txo cov neeg ua haujlwm. |
| Hluav Taws Xob | 4-Chlorobenzaldehyde yog combustible. |
| Txoj Kev Purification | Crystallize nws los ntawm EtOH / dej (3: 1), ces sublime nws ob zaug ntawm ~ 50o / 2mm. [Beilstein 7 H 235, 7 IV 568.] |
