✦ Synopsis

In investigating the kinetics of the transesterification reactions of dimethyl terephthalatc with ethylene glycol, determination of the product distribution isachieved by gas-liquid chromatographic analysis. Silylation of hydroxyl groups prior to chromatography was found to be necessary in obtaining reproducible results for the glycol esters of terephthalic acid. Silylation prolonged the analysis but yielded excellent data.

Suspensions of Chlorella vulgaris were allowed to photosynthesise with two concentrations of (14)CO2 (101 and 543 ppm) in 80% oxygen, and the incorporation of (14)C into glycolate and 3-phosphoglyceric acid (3-PGA) was followed.

A sample work-up method for gas chromatographic profiling of polyoxyethylene glycol (PEG)-related compounds in pharmaceutical matrices is described. After a short sample clean-up, carbon-oxygen linkages are partially cleaved with 0.07 M boron tribromide in dichloromethane at room temperature. The re
