Abstract
3,6-Dimethylol spiro [3.3] heptane is made by dissolving 3.6-dicarbomethoxy spiro [3.3] heptane in ether and reducing it with lithium aluminium hydride.ALSO:Linear copolyesters containing spiro-[3,3]-heptane rings and suitable for the manufacture of readily dyeable fibres and films are made by reacting (a) spiro-[3,3]-heptane-3,6-dicarboxylic acid, another dicarboxylic acid and a dihydric alcohol, or (b) 3,6-dimethylol spiro-[3,3]-heptane, another dihydric alcohol and a dicarboxylic acid, or (c) spiro-[3,3]-heptane-3,6-dicarboxylic acid, another dicarboxylic acid, 3,6-dimethylol spiro-[3,3]-heptane and another dihydric alcohol. Suitable other acids are adipic, sebacic, 4,41-diphenyldicarboxylic, 2,5-thiophenedicarboxylic, or pyridine-2,5-dicarboxylic acid or acids of formula <FORM:0984150/C3/1> where R is a bivalent radical, e.g. -CH2-, -CH2-CH2-, -CH = CH- -CH2OCH2-or -SO2-. The other dihydric alcohol may be ethylene-, trimethylene-, tetramethylene-, neopentyl-, diethylene- or p-xylylene glycol or 1,4-dimethylol cyclohexane. Ester-forming derivatives of the acids and/or alcohol may be used. In examples, copolyesters are made by reacting (1) spiro-[3,3]-heptane-3,6-dicarboxylic acid dimethyl ester, dimethyl terephthalate and ethylene glycol; (2) spiro-[3,3]-heptane-3,6-dicarboxylic acid dimethyl ester and ethylene glycol followed by the addition of bis-(b -hydroxyethyl) terephthalate and further reaction; (3) spiro-[3,3]-heptane-3,6-dimethylol and dimethyl terephthalate, followed by the addition of bis-(b -hydroxyethyl) terephthalate and further reaction.
