The β-alkylated secondary alcohols were obtained in moderate to good yields with water formed as the byproduct through a borrowing hydrogen pathway. β-Alkylation of cholesterols was also effectively achieved.

Holloway, London N7 8DB United Kingdom. August 1983 CRITICAL EVALUATION: Data obtained by Palmer et aZ (1) and by Devyatykh et aZ (2) have been discussed in detail by Gerrard (3). Mole fraction solubilities calculated from measurements by Palmer et aZ. fall into a consistent pattern with a lower solubility in hydrogen bonded solvents compared with other solvents. There is also an increase in mole fraction solubility with increase in chain length in the case of straight chain alkanes. Solubilities are in the order: in benzene < in cyclohexene < in cyclohexane and in benzene < in toluene < in xylene. The variation of solubility in nitrobenzene, with change in temperature, was measured by both Palmer et aZ. and by Devyatykh et aZ. The ratio V01'PH3/vOl'solvent for a temperature of 295.2 K has been estimated by the compiler from data given by Devyatykh et aZ. to be 8.4. This may be compared with the value of 3.06 given by Palmer et aZ. for a pressure of 1 atm. There is a similar discrepancy between the solubility in liquid paraffin calculated from the data of Devyatykh et aZ and that measured by Palmer. There is also a marked difference between the solubility of phosphine in didecyl phthalate calculated from data given by Devyatykh and that in dibutyl phthalate measured by Palmer. Expressed as V01'PH3/vOl'solvent at 295.7 K the former gives 22.2 and the latter 3.23.

  • Synthesis of Cyclohexene the Dehydration of Cyclohexanol
    Synthesis of Cyclohexene The Dehydration of Cyclohexanol. The general approach towards carrying out an organic reaction: (1) Write out the balanced reaction, using structural formulas. (2) Construct a table of relevant information for reactants and products – e.g., MPs, BPs, MWs, densities, hazardous properties. (3) Calculate the correct molar ratios of reactants. Convert moles to grams and milliliters. (4) Mix correct amounts of reactants, solvents, catalysts in correct order to give specific concentrations. Possibly heat or cool or irradiate with UV light, allow to react for necessary amount of time, possibly follow reaction progress using chromatography (e.g., TLC, GC) or spectroscopy (e.g., IR, NMR). (5) After reaction is complete, the reaction mixture is usually a complex mixture of desired product(s), byproducts, unreacted starting materials, solvents, and catalyst. Product may be light, heat, or air (O2) sensitive. (6) Separation and purification steps (so-called reaction work-up). Some combination of extractions, distillations, recrystallizations, chromatography, etc are used for the work-up. (7) Identify product(s) using spectroscopy (IR, NMR, etc), chromatography (GC, TLC, etc), physical properties (MP, BP, etc), and occasionally chemical tests. Cyclohexene. In the presence of a strong acid, an alcohol can be dehydrated to form an alkene. The acid used in this experiment is 85% phosphoric acid and the alcohol is cyclohexanol. The phosphoric acid is a catalyst and as such increases the rate of reaction but does not affect the overall stoichiometry. It can be seen from the balanced reaction that 1 mole of alcohol produces 1 mole of alkene. The theoretical yield of alkene in moles is therefore equal to the number of moles of alcohol used.

The atmospheric fate of a series of saturated alcohols (SAs) has been evaluated through the kinetic and 12 reaction product studies with the main atmospheric oxidants. These SAs are alcohols that could be used as fuel 13 additives. Rate coefficients (in cm3 molecule−1 s−1 unit) measured at 298K and atmospheric pressure (720 20 −10 14 Torr) were as follows: k1 (E-4-methyl-cyclohexanol + Cl) = (3.70 ± 0.16) × 10 , k2 (E-4-methyl-cyclohexanol + -−11 −15 15 OH) = (1.87 ± 0.14) × 10 , k3 (E-4-methyl-cyclohexanol + NO3) = (2.69 ± 0.37) × 10 , k4 (3,3-dimethyl-1- −10 −12 16 butanol + Cl) = (2.69 ± 0.16) × 10 , k5 (3,3-dimethyl-1-butanol + OH) = (5.33 ± 0.16) × 10 , k6 (3,3-dimethyl- −10 −12 17 2-butanol + Cl) = (1.21 ± 0.07) × 10 and k7 (3,3-dimethyl-2-butanol + OH) = (10.50 ± 0.25) × 10 .

Box 999, Richland, Washington 99352, United States ‡ Department of Chemistry and Catalysis Research Center, TU München, Lichtenbergstrasse 4, 85748 Garching, Germany *S Supporting Information ABSTRACT: The reaction mechanism of solid-acid-catalyzed phenol alkylation with cyclohexanol and cyclohexene in the apolar solvent decalin has been studied using in situ 13C MAS NMR spectroscopy. Phenol alkylation with cyclohexanol sets in only after a majority of cyclohexanol is dehydrated to cyclohexene. As phenol and cyclohexanol show similar adsorption strength, this strict reaction sequence is not caused by the limited access of phenol to cyclohexanol, but is due to the absence of a reactive electrophile as long as a significant fraction of cyclohexanol is present. 13C isotope labeling demonstrates that the reactive electrophile, the cyclohexyl carbenium ion, is directly formed in a protonation step when cyclohexene is the coreactant. In the presence of cyclohexanol, its protonated dimers at Brønsted acid sites hinder the adsorption of cyclohexene and the formation of a carbenium ion. Thus, it is demonstrated that protonated cyclohexanol dimers dehydrate without the formation of a carbenium ion, which would otherwise have contributed to the alkylation in the kinetically relevant step. Isotope scrambling shows that intramolecular rearrangement of cyclohexyl phenyl ether does not significantly contribute to alkylation at the aromatic ring.

  • Dehydration of Cyclohexanol – Preparation of an Alkene CHM 220
    Dehydration of Cyclohexanol – Preparation of an Alkene CHM 220 INTRODUCTION Earlier this semester you reacted an alcohol (n-butanol) with a Hydro-halide acid (Hydro-bromic Acid) to generate an alkyl halide. This reaction occurred through the SN2 pathway. In this experiment you will react an alcohol (cyclohexanol) utilizing an acid catalyst (sulfuric acid) to “dehydrate” the alcohol and form an alkene (cyclohexene). Alcohols are frequently converted into the desired alkene using an acid catalyzed Elimination reaction. The term “dehydrate” means to remove water and is used to identify the nature of the atoms/molecules eliminated to form the double bond of the alkene in our product. Primary (1O) alcohols require strong acids and significant amounts of heat (up to 180O C or more). Secondary alcohols (2O) are somewhat easier to dehydrate requiring slightly lower temperatures, where Tertiary (3O) alcohols will undergo dehydration at room temperature or only slightly above that. The dehydration of cyclohexanol follows the E1 mechanistic pathway. The dehydration reaction involved three steps. First to occur is the protonation of the alcohol by the acid, in the process the Hydroxyl- group is converted from a poor leaving group to a good leaving group. This then result is the formation of a 2O carbocation intermediate in the second step. Finally, we generate an alkene following the loss of a proton adjacent to the carbocation. OH OH2 + + H2SO4 HSO4 OH2 + H2O + + HSO4 H2SO4 H In each case these reactions are reversible and are under conditions of equilibrium. Since each step is in equilibrium we must make use of Le Chatelier’s principle to drive the reaction in the desired direction.

Examples of TPE’s include: Santoprene, Nitrile (TPE) and Hytrel. TPE’s are manufactured using a plastic injection molding process where the resin, or diaphragm material, is melted and injected into a mold to produce the diaphragm. The advantages of this process includes: Features Benefits Diaphragm is molded to optimum shape Excellent flex life Homogenous part No delamination failures High performance resins Chemical, abrasion and flex life Injection molded/tight process control Low cost/consistent performance Laboratory testing has shown: Injection Mold Process Santoprene outperformed all rubber diaphragms except Buna in the mild abrasive fluids.
