The general specifications of commercially available hydroxypropylated /3-cyclodextrins (HPBCDs) usually give information on the solubility, solubilizing potency and average degree of substitution (DS) of a given product. The DS value is regarded as suitable for quality control purposes. This paper
## Abstract Samples of vegetable oils were oxidized at isothermal conditions in the cell of a Pressure Differential Scanning Calorimeter (PDSC) and in the __Methrom Rancimat__ apparatus. The PDSC and __Rancimat__ experiments were carried out at a temperature in the range of 90β160β Β°C. From resultin
The kinetic parameters of the complex reaction between phenol and formaldehyde in the presence of sodium hydroxide (NaOH) have been obtained by differential scanning calorimetry (DSC). The two dominant reactions appear to be addition of formaldehyde to phenol with formation of o-hydroxymethyl-phenol
