Dinonyl phthalate

Compounds of intermediate polarity which possess a polar or polarisable group attached to a large non-polar skeleton, e.g. esters of high-molecular-weight alcohols such as dinonyl phthalate. 

Shen et al. have reported studies on procaine-selective electrodes embodying PVC membranes [57]. Various ion-pair complexes (procaine derivatives with tetraphenylborate, dipicrylamine, tetraiodomecurate, and reineckate) were incorporated into platinized PVC membranes, and with dinonyl phthalate as the solvent mediator, formed procaine selective electrodes. The efficiency and performance of these were compared, and it was found that procaine picrylamine and procaine tetraphenylborate were the best electroactive materials. The procaine picrylamine electrode exhibited a Nemstian response over the range 10 pM to 0.1 M, and was used as the indicator electrode for the potentiometric determination of procaine. The method recovery was found to be 99.8%, with a standard deviation of 0.9%.

Ether was added to break the emulsion, and the soln was washed twice with water, and dried (CaCl2). After evaporating the ether, the residual liquid was distd three times under reduced pressure. It was stored in a vacuum desiccator over P2O5...

Several gas chromatographic separations of phenols from plasticizers have been accomplished. Dinonyl phthalate (25) or silicone oil (20) are recommended as column materials. Saponification is best carried out in glycolic potassium hydroxide, which, for example, saponifies tricresyl phosphate quantitatively. 

Furans have been separated on columns using tricresyl phosphate, triethylene glycol and dinonyl phthalate stationary phases, often with Chromosorb as a support.

Analysis of a mixture of ketones, (a) Qualitative analysis. The following instructions for the packing of a standard 1.5-m length, 4-mm diameter glass column with a 10 per cent dinonyl phthalate on Chromosorb W support can be taken as indicative of the general technique appropriate to the packing of a column.
