Abstract

1,237,338. Trialkylammonium germates. DYNAMIT NOBEL A.G. 7 Nov., 1969 [28 Nov., 1968], No. 54728/69. Heading C2C. [Also in Division C3] Triethylammonium, tri-n-propylammonium and triisopropylammonium germanates are prepared by adding the corresponding amine gradually to a suspension of germanium dioxide in ethylene glycol containing a small amount of water, at 85-100‹ C. The solution obtained is used as a catalyst for preparing poly(ethylene terephthalate).
