Title: Recovery of germanium
Inventor: NAGAI HIROSHI
IPC: C01G17/02
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To provide a method for economically recovering germanium used as a catalyst for producing polyethylene terephthalate in a reutilizable purity by using a simple apparatus. SOLUTION: This method for recovering germanium used as a catalyst from a waste rejected when producing polyethylene terephthalate or a polyester consisting essentially thereof comprises initially inicinerating the waste, then distilling the resultant ash with hydrochloric acid, recovering a condensate containing germanium tetrachloride, separating the germanium tetrachloride from the recovered condensate, hydrolyzing the prepared germanium tetrachloride and affording germanium dioxide. In the method, the obtained germanium dioxide can be roasted to remove impurities. The condensate after separating the germanium tetrachloride is reovered by circulation thereof and the resultant hydrolyzate after separating the germanium dioxide can be electrodialyzed to recover the germanium dioxide and hydrochloric acid.

Title: Heat-shrinkable polyester film
Inventor: ISAKA TSUTOMU
IPC: B29C61/06
Filed: 1987-06-25
Abstract: PURPOSE:To give the stable heat shrinkability and beautiful and strong packaging state and to improve the stability and heat resistance in a printing pitch, by making use of a polyester film which is mainly composed of terephthalic acid and ethylene glycol and composed of neopenthyl glycol as a copolymeric ingredient and possesses a specific heat shrinkage factor and intersection shrinkage factor. CONSTITUTION:The title film is mainly composed of terephthalic acid and ethylene glycol. Then the title film is a polyester film composed of a composition containing copolymer polyester composed of neopentyl glycol as a copolymeric ingredient. Accordingly, the title film possesses distinctive characteristics that a heat shrinkage factor in at least either unidirection of a longitudinal and lateral directions of the film within hot air of 100 deg.C is 30%. Then the film is obtained by orienting four times or more at an intersection shrinkage factor of 5% or more. It is preferable that a residual quantity of the neopentyl glycol falls within a range of 3-40mol.% within the whole composition. In the case where the same is less than 3mol.%, holding time of inner residual stress becomes short. On the one hand, when the neopentyl glycol exceeds 50mol.%, it has no effect of improving the holding time of residual stress at the time of heat treatment and progress of noncrystallizability and carrying-resistant properties deteriorate.
