| 2-Methyltetrahydrofuran-3-un Defnydd a Synthesis |
| Disgrifiad | 2-Methyltetrahydrofuran-3-mae gan un brifnodyn bara menyn. Gellir ei baratoi trwy ddatgarbocsio hydrolytig o 2-methyl-4-carbomethoxytetrahydrofuran- 3-un; trwy gau cylch asid-catalyzedig o p-alcocsi-diazoketones. |
| Priodweddau Cemegol | 2-Methyltetrahydrofuran-3-mae gan un arogl sy'n atgoffa rhywun o wyrdd y gaeaf. |
| Priodweddau Cemegol | Di-liw i hylif melyn golau |
| Achlysur | Adroddwyd wedi'i ganfod fel cyfansoddyn mewn arogl coffi; hefyd fel elfen blas anweddol mewn cnau filbert rhost. Adroddwyd hefyd mewn guava, rhesins, pîn-afal, nionyn, tatws pob a ffrio, tomato, bara gwenith, bara creision, pysgod mwg, cig eidion a phorc wedi'u coginio, iau porc, rym, coco, coffi, cnau daear, sglodion tatws, ffrwythau angerdd, ffa , madarch, tamarind, tatws melys, licorice, brag, bonito sych, cherimoya, okra a maté |
| Defnyddiau | 2-Methyltetrahydro-3-mae furanone wedi cael ei ddefnyddio fel atalydd synhwyro cworwm-moleciwl i ymchwilio i'w effaith ar dwf a ffurfiant bioffilm mewnHafnia alvei. |
| Diffiniad | ChEBI: Mae dihydro-2-methyl-3(2H)-furanone yn aelod o oxolanes. |
