N-Butyl chloride

Alternatively, use the equivalent amount of n-butyl chloride and prepare the Grignard reagent as for aec.-biltyl magnesium chloride. 

About 20 g. of n-butyl chloride, b.p. 76-80°, may be recovered by carefully rofractioiiating the distillate that passes over below 86°.

Atomized lithium (26 g, 3.75 mols) and sodium-dried ether (200 cc) are placed in a 3-liter, 3-necked flask fitted with a Herschberg stirrer, thermometer pocket and a water condenser closed by a calcium chloride tube. A slow stream of dry nitrogen is blown through the flask, which is cooled to -10°C and n-butyl chloride (138 g, 156 cc, 1.5 mols) is run in with rapid stirring the mixture is stirred for a further 30 minutes, and then cooled to -60°C... 

In the chemical process industry molybdenum has found use as washers and bolts to patch glass-lined vessels used in sulphuric acid and acid environments where nascent hydrogen is produced. Molybdenum thermocouples and valves have also been used in sulphuric acid applications, and molybdenum alloys have been used as reactor linings in plant used for the production of n-butyl chloride by reactions involving hydrochloric and sulphuric acids at temperatures in excess of 170°C. Miscellaneous applications where molybdenum has been used include the liquid phase Zircex hydrochlorination process, the Van Arkel Iodide process for zirconium production and the Metal Hydrides process for the production of super-pure thorium from thorium iodide. 

Bordwell and Cooper211 drew attention to the inertness of a-halosulfones and related compounds towards nucleophilic displacements of the halogen. Thus chloromethyl p-tolyl sulfone reacts with potassium iodide in acetone at less than one-fiftieth of the rate for n-butyl chloride. On the other hand, l-(p-toluenesulfonyl)-3-chloro-l-propene reacts about 14 times faster than allyl chloride. This contrast (and other comparisons) led the authors to attribute the inertness of a-halosulfones to steric hindrance, which was eliminated when the sulfonyl group was more remote from the reaction center. 

Two-dimensional thin-layer chromatography. This method is used to verify the presence of terminal 5-sultones, terminal unsaturated y-sultone, and terminal 2-chloro-y-sultone, if they are detected in the gas chromatographic determination. After extraction of the neutral oil from the AOS sample, the neutral oil is made up volumetrically to at least a 10% solution in hexane. Of this solution 3 pi is spotted onto a silica gel TLC plate together with standard sultones. It is twice developed with 2-propyl ether and then after turning the plate 90° twice developed with 60/40 n-butyl chloride/methylene chloride. The... 

The electroreduction of CHT in DMF in the presence of n-butyl chloride gives, for example, 6-butyl-l,3-cycloheptadiene as the main product (equation 26). This selectivity in alkylation is interesting, since it is also known that the reductive butylation of CHT using Li/NH3 as the reducing agent gives a mixture of 5-butyl-l,3-cycloheptadiene and 3-butyl-l,4-cycloheptadiene in which the latter is the main product22,23. 

The Friedel-Crafts alkylation of 2,5-dimethylthiophene was also studied (57). In contradistinction to thiophene itself, it was reported that this substituted thiophene alkylated readily with only a minor amount of polymerization when an active halide such as t-butyl chloride was used. With less reactive halides, e.g. n-butyl chloride, some replacement of the methyl groups in 2,5-dimethylthiophene occurred and polymerization increased.
