One proposal suggested injecting chlorosulfonic acid
, a highly corrosive and toxic substance, into the engine exhaust.
Fifty milliliter of chlorobenzene was charged into a round-bottomflask equipped with a mechanical shaker and connected to a dropping funnel filled with a stoichiometrical amount of chlorosulfonic acid
During the next few years, the company tested smoke pots, smoke candles, and smoke dispensers filled with sulfur trioxide in chlorosulfonic acid
(FS) to establish operational doctrine.
The next big breakthrough came in 2009, when Talmon, Pasquali and colleagues discovered the first true solvent for nanotubes -- chlorosulfonic acid
The researchers have reported that chlorosulfonic acid
can dissolve half-millimeter-long nanotubes in solution, a critical step in spinning fibres from ultralong nanotubes.
Synthesis of the sulfuric acid monoester from epoxidized methyl ester is accomplished by the reaction of epoxidized methyl esters with chlorosulfonic acid
in pyridine solution.
It had been hoped to use chlorosulfonic acid
for item (f), and sulfur dichloride or monochloride for (g).
The emergency exercise simulated a rail tank car derailment causing the "spill" of chlorosulfonic acid
, a raw material used in Rhodia's Baltimore plant.
This stage included the surface modification of sodium montmorillonite nanoparticles by using chlorosulfonic acid
, and carrying out the required tests.
The researchers took advantage of novel cryogenic techniques for electron microscopy that allowed them to directly image the graphene sheets in the chlorosulfonic acid
Pasquali, primary author Nicholas Parra-Vasquez and their colleagues reported this month in the online journal ACS Nano that chlorosulfonic acid
can dissolve half-millimeter-long nanotubes in solution, a critical step in spinning fibers from ultralong nanotubes.
3]and its complexes, such as acyl and alkyl sulfates and chlorosulfonic acid
, are commonly used as sulfonating agents.
