Synthesis of esters by the carbalkoxylation of olefins with carbon monoxide

Uptake of Methanol by Poly(methyl methacrylate): An Old Problem Addressed by a Novel Raman Technique

“…This could be caused either by an altered focal volume due to changes in the refractive index or a nonideal mixing behavior of MMB and methanol. The refractive indices of the neat liquids MMB (n D 20 = 1.393 44 ) and deuterated methanol (n D 20 = 1.326 according to the manufacturer) are close to each other. Further, for all measurements, an excess of MMB was used, and thus, the contribution of MMB should predominate the refractive index of the mixture.…”

Energies of the cycloalkyl and 1-methylcycloalkyl free radicals by the decarbonylation method

“…1-Methylcyclopentanecarboxaldehyde: The products were methylenecyclopentane,56 1-methylcyclopentene,57 1-chloro-l-methylcyclopentane,54 and ethyl 1-methylcyclopentanecarboxylate. 48 The first two products were shown to arise from the third in the injection port of the gas chromatograph. The analysis was done on column A, programmed between 50 and 233 °C.…”

“…Cyclopentanecarboxaldehyde: The products were chlorocyclopentane and ethyl cyclopentanecarboxylate. 48 The analysis was done on column B, programmed between 50 and 230 °C. A control showed that a mixture of chlorocyclopentane and cyclopentanecarbonyl chloride did not change composition when included in a decarbonylation run of cyclobutanecarboxaldehyde.…”
