Anhydrous stannous chloride, a water-soluble white soHd, is the most economical source of stannous tin and is especially important in redox and plating reactions. Preparation of the anhydrous salt may be by direct reaction of chlorine and molten tin, heating tin in hydrogen chloride gas, or reducing stannic chloride solution with tin metal, followed by dehydration. It is soluble in a number of organic solvents (g/100 g solvent at 23°C) acetone 42.7, ethyl alcohol 54.4, methyl isobutyl carbinol 10.45, isopropyl alcohol 9.61, methyl ethyl ketone 9.43 isoamyl acetate 3.76, diethyl ether 0.49, and mineral spirits 0.03 it is insoluble in petroleum naphtha and xylene (2). 

Preparation of 4-aza-S-(N-methyl-4-piperidyll-10,11-dihydro-SH-dibenzo[a,d]cycloheptene-S-ol Add 17.4 g of N-methyl-4-chloropiperidine to a stirred mixture containing 3.2 g of magnesium, 20 ml of anhydrous tetrahydrofuran, 1 ml of ethyl bromide and a crystal of iodine. Reflux for two hours, cool to 30°-35°C and add a solution of 13 g of 4-aza-10,11 -dihydro-5H-dibenzo[a,d] cycloheptene-5-one in 25 ml of tetrahydrofuran. Stir for five hours, remove the solvent by distillation in vacuo and add 250 ml of ether. Add 100 ml of 10% ammonium chloride solution and extract the mixture with chloroform. Concentrate the chloroform solution to a residue and recrystallize from isopropyl ether obtaining 20 g of the carbinol,... 

An interesting case of interproduct competition is that of the four original lacquer solvents—ethyl alcohol, butyl alcohol, ethyl acetate, and butyl acetate. These were once produced mainly by fermentation processes, but today all are also produced by synthesis from petroleum hydrocarbons. Moreover, in the past 30 years solvents have been developed from petroleum sources which are competing successfully with these materials even though the new compounds are not identical in all properties isopropyl alcohol competes with ethyl alcohol methyl isobutyl carbinol and n-propyl alcohol can replace butyl alcohol methyl ethyl ketone to a large extent supplants ethyl acetate and methyl isobutyl ketone can be substituted for butyl acetate. Thus, petroleum aliphatic chemicals have served both by displacement of source and replacement of end product to supplement and to compete with the fermentation solvents. 

ETHYL CARBINOL (71-23-8) Forms explosive mixture with air (flash point 59°F/15°C). Violent reaction with strong oxidizers, potassium-tert-butoxide, triethylaluminum. Reacts, possibly violently, with acetaldehyde, alkalineearth and alkali metals, strong acids, strong caustics, aliphatic amines, benzoyl peroxide, chromic acid, chromium trioxide, dialkylzincs, dichlorine oxide, ethylene oxide, hypochlorous acid, isocyanates, isopropyl chlorocarbonate, lithium tetrahydroaluminate, nitric acid, nitrogen dioxide, nitronium tetrafluoroborate(l-), penta-fluoroguanidine, phosphorus pentasulfide, tangerine oil, triisobutylaluminum. Attacks some plastics, rubber, and coatings. 

Cyclopropyl thien-2-yl ketone (34), available commercially, was subjected to a Grignard reaction with 21 to yield a carbinol (31) in excellent yield. Bromotrimeth-ylsilane-mediated opening of the cyclopropyl ring led to the 4-bromo derivative 32. Condensation with ethyl i -(-)-pipeildme-3-carboxylate (16) was conducted in isopropyl acetate as a solvent with anhydrous lithium carbonate as the base. The transformation was cleaner and did not provide any of the diene (26) arising from elimination of hydrogen bromide. The alkylation of the nipecotate residue could also be directly effected with a mixture of the tartrate salt of 16, lithium carbonate, and isopropyl acetate. Compound 33 was readily isolated as the hydrochloride isopropyl acetate was superior to all other solvents used in this reaction. Since it is not itself prone to hydrolysis, it is preferable to ethyl acetate. Moreover, it appears to crystallize hydrochlorides much better.

The ketone/carbinol ratio would then depend on competition between the elimination and substitution reactions, and since a bulky / group should favour elimination, the ratio should increase as R changes from ethyl to isopropyl to isobutyl, as in fact it does. The mechanism also accounts for the difference between 2-picoline and 3- and 4-picoline5 .
