    Abstract: 1,148,456. Dihydrotricyclopentadienylamine. BADISCHE ANILIN- & SODA-FABRIK A.G. 8 June, 1966 [9 June, 1965], No. 25518/66. Heading C2C. [Also in Division C3] The invention comprises a dihydrotricyclopentadienylamine having the formula and a process for the preparation thereof wherein tricyclopentadiene is reacted with at least five up to twenty moles of hydrocyanic acid and sulphuric acid in the proportion of more than one but not more than three moles per mole of tricyclopentadiene in the presence of one to three moles of a di-n-alkyl ether at a temperature of from - 5‹ to + 35‹ C. and hydrolysing the resultant N-dihydrotricyclopentadienyl formamide. The product is a rubber accelerator. Examples are furnished.

    Abstract: A process for preparing formic acid by thermal cleavage of quaternary ammonium formates of the general formula I (* CHEMICAL STRUCTURE *) (I) where R1, R2 and R3 are C1- to C14-alkyl, C3- to C8-cycloalkyl, aryl or C7- to C16-aralkyl, or together are 1,4- or 1,5-alkylene which is unsubstituted or substituted one to four times by C1-to C4-alkyl, with the proviso that the sum of the carbon atoms of R1, R2 and R3 in the quaternary ammonium formates I is 7 to 40, comprises carrying out the cleavage in the presence of secondary formamides of the general formula II (* CHEMICAL STRUCTURE *) (II) where R4 and R5 are C2- to C10-alkyl, C3- to C8-cycloalkyl, aryl or C7- to C16-aralkyl, or together are 1,4- or 1,5-alkylene which is unsubstituted or substituted one to four times by C1- to C4-alkyl, which formamides boil 30 degrees to 150 degrees C. lower than the tertiary amine of the general formula III (* CHEMICAL STRUCTURE *) (III) where R1, R2 and R3 have the abovementioned meanings, contained in the formate I.
