    摘要: Wellbore liner apparatus has been invented which, in one aspect, includes at least one tubular member for lining at least part of a lateral wellbore extending from a primary wellbore in the earth, at least one coupling bushing connected to the at least one tubular member and disposed in the primary wellbore, the coupling bushing having a bore therethrough from a top to a bottom thereof. In one aspect, the wellbore liner apparatus has two coupling bushings and a first tubular member and a second tubular member, the first tubular member secured to and extending down from the first coupling bushing to the second coupling bushing which is secured thereto, the second tubular member secured to and extending down from the second coupling bushing, with part of the second tubular member lining the lateral wellbore. Such systems are combinable with a wellbore milling system so that communication between the primary wellbore and the interior of the liner may be reestablished.

    摘要: One process comprises the step of reacting an amount of 5-carboxy-2-pyridone directly with both a suitable chlorinating agent and a suitable fluorinating agent to selectively transform both the 5-carboxy group and the 2-positioned oxygen function of the ring. A second process comprises the steps of reacting an amount of 5-carboxy-2-pyridone with a suitable fluorinating agent to selectively transform the 5-carboxy group without altering the 2-positioned oxygen function of the ring and reacting the 5-trifluoromethyl-2-pyridone thereby formed with a suitable chlorinating agent to cause 2-chloro-5-trifluoromethylpyridine to form. A third process comprises the steps of reacting an amount of a 5-carboxy-2-pyrone compound with a suitable fluorinating agent to selectively transform the 5-carboxy group without altering the 2-positioned oxygen function of the ring, reacting the 5-trifluoromethyl-2-pyrone compound thereby formed with an ammonia-containing agent in the presence of a caustic material to cause 5-trifluoromethyl-2-pyridone to form, and reacting the 5-trifluoromethyl-2-pyridone thereby formed with a suitable chlorinating agent to cause 2-chloro-5-trifluoromethylpyridine to form.

    摘要: An improved process for preparing the 2-alkylamino-5-alkylpyridine and 2-amino-5-alkylpyridine amination products of 3-alkylpyridines, comprising the step of initially reacting the base directly with the sodium salt of a primary alkylamine to produce the 2-alkylamino form, wherein the alkyl group in each reactant has from 1 to about 20 carbon atoms. The sodium salt is preferably preformed in situ by adding the alkylamine to a dispersion of sodium in an organic solvent heated to about 100.degree.-120.degree. C. The substituted amination preferably proceeds at a temperature of about 100.degree.-140.degree. C. in a solvent such as toluene and under an inert nitrogen atmosphere. The ratio of 2,5-:2,3- isomer products of the reaction is up to about 10:1 or more, with the effective yield of the 2,5-alkylated isomer being about 25% or more. This recovered 2-alkylamino-5-alkylpyridine product is readily dealkylated by reaction with hydrobromic or hydriodic acid with or without the presence of a pyridine hydrohalide salt to obtain the 2-amino-5-alkylpyridine product which has proven uses in herbicidal, insecticidal and pharmaceutical applications.
