Kinetics of acyl chloride reactions with diols

Reactions of enantiopure cyclic diols with sulfuryl chloride.

Monocyclic allylic cis-1,2-diols reacted with sulfuryl chloride at 0 °C in a regio- and stereo-selective manner to give 2-chloro-1-sulfochloridates, which were hydrolysed to yield the corresponding trans-1,2-chlorohydrins. At -78 °C, with very slow addition of sulfuryl chloride, cyclic sulfates were formed in good yields, proved to be very reactive with nucleophiles and rapidly decomposed on at...

Reactions of Chromyl Chloride with Monocarboxylic Acids

Chromyl chloride was prepared by the literature method 3. A solution of formic acid in carbon tetra­ chloride was added dropwise to chromyl chloride diluted in the same solvent so that the reaction product was always in excess of formic acid. Since the reaction was violently exothermic, the reaction vessel was maintained at 0 °C throughout the addition. After a few minutes, the colour of the so...

Kinetics of Benzyl Chloride Production in a Bench Reactor Under Pressure with Stirrer (TECHNICAL NOTE)

Benzyl chloride is economically one of the most important starting materials for a large number of industrial syntheses. Far too much money is now spent to buy and import this valuable product. The production of benzyl chloride has been recognized as one of our national projects and budgeted by the National Iranian Petrochemical Organization in order to economize on the country’s foreign exchan...

Kinetics of Ballistically-Controlled Reactions

We investigate the kinetics of generic single-species reaction processes when the reactants move ballistically, namely ballistic annihilation, A + A 0, and a ballistic aggregation process which mimics traffic flow on a single-lane roadway. For ballistic annihilation, dimensional analysis shows that the concentration and root means square velocity decay as c P and u N r-6, respectively, with a +...
