In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Formula: C5H8O2, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1679-47-6, name is 3-Methyldihydrofuran-2(3H)-one. In an article，Which mentioned a new discovery about 1679-47-6
Volatile compounds from fresh and dried mango were extracted by the solvent-assisted flavour evaporation (SAFE) technique and analysed by GC-MS. Forty-one and fifty five volatile compounds were identified in fresh and dried mango, respectively. Monoterpenes, followed by sesquiterpenes, lactones and alcohols were the major compounds. Drying induced substantial losses of several compounds. The total amount of volatiles decreased by about 59%. These losses could be mainly attributed to the evaporation of the volatiles during drying, the extent of which seemed to increase with the hydrophobicity and Henry’s law constant of the compounds. However, new compounds appeared and enrichment of some compounds was observed after drying. Limonene, beta-myrcene, delta-3-carene, beta-caryophyllene, gamma-butyrolactone and 3-methylbutyl butanoate were found to be flavour contributors in both products on the basis of the odour activity values (OAVs). Mesifuran displayed high OAV only in fresh fruit while hexanal and heptanal only in dried mango.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1679-47-6, help many people in the next few years.Formula: C5H8O2
