2-Methylbenzophenone oo leh CAS 131-58-8
2-Methylbenzophenone waa isku-dhis benzophenone ah, kaas oo ah kiimiko aad muhiim u ah. Isla mar ahaantaana, ketones-ku sidoo kale waa qaab-dhismeedka asaasiga ah ee molecules badan oo organic ah, sida walxaha shaqeynaya, caraf udgoonka iyo molecules-ka daawada. Ketones-ka udgoonku waa baloogyo dhisme oo aad muhiim u ah oo ku jira isku-darka organic-ga, kuwaas oo si weyn uga jira qaab-dhismeedka asaasiga ah ee alaabada dabiiciga ah waxaana si weyn loogu isticmaalaa isku-dhisyo firfircoon oo bayoloji ahaan firfircoon.
| Shay | Heerka Caadiga ah |
| Muuqaalka | Dareere aan midab lahayn oo huruud khafiif ah |
| Baaritaan | ≥99.0% |
| Biyo | ≤0.20% |
Iyada oo la ilaalinayo gaaska aan firfircoonayn, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol%) iyo biquinoline (bq, 3 mol%) ayaa lagu kala firdhiyey dareere dabiici ah (2 mL)), ka dibna H2O (2 mmol) ayaa lagu daray, heerkulkana waxaa kor loogu qaaday 80°C muddo 6 saacadood ah. Kadib xalka falcelinta waxaa la soo saaray saddex jeer iyadoo la adeegsanayo Et2O (5 mL), marxaladaha dabiiciga ah ayaa la isku daray, dareerahana waa la qalajiyey iyadoo cadaadis yar la dhimay. Badeecada cayriin ee la helay waxaa lagu sameeyay koromatografi tiir oo ku yaal tiir jel silica ah (300-400 mesh), qaybahana waxay ahaayeen batrool ether, si loo helo badeecada bartilmaameedka ah 2-methylbenzophenone. Sifooyinka kiimikada Dareere aan midab lahayn ama huruud khafiif ah oo hufan. Barta dhalaalku waa qiyaastii 134°C. Isticmaal dhexdhexaad daawo ahaan.
