    Abstract: 1,135,472. Tetrahydrotricyclopentadiene diamine. BADISCHE ANILIN- & SODAFABRIK A.G. 25 March, 1966 [27 March, 1965], No. 13252/66. Heading C2C. [Also in Division C3] Tetrahydrotricyclopentadiene diamine is prepared from tricyclopentadiene by injecting the molten hydrocarbon into a mixture of HCN and H 2 SO 4 , adding water, distilling off any excess HCN, adding NaOH, extracting with cyclooctylamine, adding benzene, washing with water and distilling.

    Abstract: 1,125,716. Urea derivatives. BADISCHEANILIN- & SODA-PABRIK, A.G. 18 Jan., 1966 [22 Jan., 1965], No. 2240/66. Heading C2C. [Also in Division A5] The invention comprises urea derivatives of the formula wherein R 1 represents CH 3 , OCH 3 or -CH(CH 3 ) C#CH; and the group R-NH- is derived from one of the amines: (a) exobicyclo-(3,3,0)- octylamine-2, (b) endo- and exobioyolo-(3,3,0)- octylamine-3 or (c) exobicyclo-(3,2,1)-octylamine-8. They may be obtained by subjecting bicyclo-(3,3,0)-octene-2 to the Ritter reaction, hydrolysing the acylamines to the corresponding amines, which are separated by preparative gas chromatography into four fractions of which the first fraction contains exo-bicyclo-(3,3,0)-octylamine-2, the second fraction endo- and exobicyclo - (3,3,0) - octylamine - 3, the third fraction endo - bicyclo - (3,3,0) - octylamine - 2 and the fourth fraction exo-bicyclo-(3,2,1)-octylamine-8; and reacting either the individual amine fractions or the amine mixture with the appropriate carbamic acid derivatives dissolved in a hydrocarbon and in the presence of an acidbinding agent or a catalyst to give each of the above ureas and 1-(endo-2-bicyclo-[3,3,0]-octyl)- 3,3-dimethylurea, or a mixture of these ureas respectively. They are useful as active ingredients in herbicidal compositions (see Division A5).

    Abstract: Polyepoxides are cured by polyamides prepared from tetrahydrotrcyclopentadienylenediamine with a dicarboxylic acid having 3 to 20 carbon atoms. Other primary and/or secondary amines may have been used in addition to the tetrahydrotricyclopentadienylenediamine in the preparation of the polyamide. Conventional acidic and basic curing agents and solvents may be added to the curable mixtures. Polyamides are prepared by heating to 150 DEG or 180 DEG C. and then to 260 DEG C. under nitrogen whilst distilling off water a reaction mixture consisting of tetrahydrotricyclopentadienyl enediamine-diethylenetriamine and (1) 1-octylnonane-1,9-dicarboxylic acid; (2) adipic acid; (3) dodecanedicarboxylic acid; or (4) 1,2 - bisaminomethylcyclohexane and 1-octylnonane -1,9-dicarboxylic acid.ALSO:Sheet steel and sheets of glass are laquered with a xylene/butanol solution of an aliphatic polyglycidyl ether and a polyamide from tetrahydrotricyclopentadienylenediamine and a dicarboxylic acid. The coatings are cured at room temperature or at 120 DEG C.
