| 2,4-Dihydroxyacetophenone Siv Thiab Synthesis |
| Chemical Properties | 2,4-Dihydroxyacetophenone tshwm li daj-xim av rau reddish-xim av zoo crystalline hmoov. Nws maj mam decomposes hauv dej thiab tuaj yeem yaj hauv dej cawv kub, pyridine, thiab glacial acetic acid. Nyob rau hauv sib piv, nws yog ze li insoluble nyob rau hauv ether, benzene, thiab chloroform. Ib qho tshuaj tiv thaiv nrog hlau chloride ua rau nws txais yuav xim liab. |
| Siv | 2,4-Dihydroxyacetophenone (cas# 89-84-9) yog ib qho khoom siv muaj txiaj ntsig zoo hauv cov organic synthesis. Nws kuj yog siv los ua cov tshuaj nruab nrab rau cov tshuaj. Reagent rau hlau raws li 10% cawv daws. Cov xim liab yog tau nrog ferric ions hauv cov kua qaub me ntsis: Cooper, Ind. Eng. Chem. Qhov quav. Ed. 9, 334 (1937). |
| Txhais | ChEBI: 2',4'-dihydroxyacetophenone yog ib qho dihydroxyacetophenone uas yog acetophenone nqa hydroxy substituents ntawm txoj haujlwm 2' thiab 4'. Nws muaj lub luag haujlwm ua cov nroj tsuag metabolite. Nws yog ib tug tswv cuab ntawm resorcinols thiab dihydroxyacetophenone. |
| Kev npaj | Kev npaj los ntawm cov tshuaj tiv thaiv acetic acid ntawm resorcinol, nrog zinc chloride (Nencki cov tshuaj tiv thaiv) (94%) nrog boron trifluoride nrog Amberlite IR -120 (ib cation txauv resin, sulfonic acid hom) (87%) nrog polyphosphoric acid (63%) nrog 70% perchloric acid (33%). |
| Synthesis Reference (cov) | Phau ntawv Journal of the American Chemical Society, 70, p. 428 Ib., 1948DOI:10.1021/j01181a521 |
| Kev ruaj ntseg Profile | Muaj tshuaj lom los ntawm kev noj tshuaj. Kev sim ua kom muaj menyuam. Qhov muag mob heev. Thaum rhuab mus rau decomposition nws emissions pa luam yeeb thiab irritating fumes. |
| Synthesis | 2, 4-Dihydroxyacetophenone yog tau los ntawm acetylation ntawm resorcinol thiab acetic acid. Tsis tas li ntawd, nws tseem tuaj yeem tau txais los ntawm reacting resorcinol nrog chloroacetyl lossis acetic anhydride nyob rau hauv muaj zinc chloride. |
