PROCESS FOR PRODUCTION OF SOLID INHIBITOR COMPOSITIONS BEING USED IN WIDW SCALE OF TEMPERATURE AND PROTECTING THE WELLS AND THEIR SORROUNDINGS PRODUCING HYDROCARBON

Inhibitor compsns. for wells producing hydrocarbons and for the surroundings of such wells are prepd. by reacting 1-80 pts. wt. (satd.) carboxylic acids having 12-18C with 1-30 pts. wt. ethylene-diamine and/or diethylene-triamine. Water formed in the reaction is completely eliminated by heating the...

Zusammenfassung:	Inhibitor compsns. for wells producing hydrocarbons and for the surroundings of such wells are prepd. by reacting 1-80 pts. wt. (satd.) carboxylic acids having 12-18C with 1-30 pts. wt. ethylene-diamine and/or diethylene-triamine. Water formed in the reaction is completely eliminated by heating the reaction mixt. to 280 deg. C and keeping it at this temp. for 5-8 hours. Subsequently 1-40 pts. wt. macrocrystalline paraffin wax of petrolatum or ceresin quality contg. not more than 20 wt.% oil is added, together with dicyclohexyl-ammonium-nitrite. The mass is cast into rod shapes after homogenisation.
