Brominated Diphenyl Ethers - an Important Step on the Way to Synthetic Lubricants

Article abstract of DOI:10.1007/BF00808278

The described synthesis of synthetic lubricants based on polyphenyl ethers requires an analytical characterization of the isomerization step, which is important to the process optimization.The separation of the intermediates succeeds with gas chromatography; the isomers are determined using a retention index system.The obtained results are compared with the composition of the final product, which was investigated by HPLC analysis.Keywords.Gas chromatography; Polyphenyl ethers; Lubricants, synthetic.
