| 유해성 요약 | Corrosive to skin[Quick CPC] Liver damage has been reported in workers after skin exposureliver injury also occurs in high-dose animal studies[HSDB] Can cause irritation of the respiratory tract and at higher concentrations pulmonary edema[NJ-HSFS] Can cause burns to skin and eyesA skin, eye, and mucous membrane irritant[CAMEO]The major hazards encountered in the use and handling of benzenesulfonyl chloride stems from its toxicologic properties. Toxic by all routes (ie, inhalation, ingestion, and dermal contact), exposure to this colorless, oily liquid may occur from its manufacture and use as a catalyst, an intermediate in the production of phenols,amides, insecticides, miticides, and acaricides, and as a reagent for Friedel-Crafts sulfonation. Effects from exposure may include contact burns to the skin and eyes, and liver damage. In activities and situations where over-exposure may occur, wear a positive pressure self-contained breathing apparatus, and chemical protective clothing which has been specifically recommended by the shipper or manufacturer. If contact should occur, immediately irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes, and wash exposed skin thoroughly with soap and water. Remove contaminated clothing and shoes at the site. While benzenesulfonyl chloride does not ignite easily, it may burn with the production of poisonous gases. Runoff from fire control water may cause pollution. For fires involvin g benzenesulfonyl chloride, extinguish with dry chemical, CO2, water spray, fog, or regular foam. Small spills of this substance may be taken up with sand or other noncombustible absorbent and placed into containers for later disposal. Large spills should first be diked far ahead of the spill. Benzenesulfonyl chloride is a potential candidate for liquid injection or rotary kilnforms of incineration. |

Since it rapidly hydrolyzes, adsorption to and volatilization from moist soil are not expected to be significant processes, although no data specifically regarding the fate of benzenesulfonyl chloride in soil were located(SRC). Based upon an estimated vapor pressure of 0.068 mm Hg at 25 deg(2,SRC), volatilization from dry near-surface soil or other surfaces may be significant processes(SRC).AQUATIC FATE: If benzenesulfonyl chloride is released to water, it will be expected to rapidly hydrolyze with a half-life of 5.1 min at 21 °C(1,SRC). Since it rapidly hydrolyzes, bioconcentration, volatilization, and adsorption to sediment and suspended solids are not expected to be significant processes(SRC). No data were located concerning biodegradation, but benzenesulfonyl chloride probably chemically hydrolyzes significantly faster than it biodegradates(SRC). Direct photolysis is not expected to be an important removal process in surface waters(2,SRC).ATMOSPHERIC FATE: If benzenesulfonyl chloride is released to the atmosphere, it will be expected to exist almost entirely in the vapor phase(1) based upon an estimated vapor pressure of 0.068 mm Hg at 25 °C(2,SRC).

An atmospheric half-life of 7.9 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm has been calculated for this process based upon an estimated rate constant(3,SRC).

| Environmental Biodegradation | No data were located concerning the biodegradation of benzenesulfonyl chloride either in natural systems or in laboratory studies(SRC).

The calculated half-life for hydrolysis at 10 °C is 12.9 min(1,SRC). The products of hydrolysis are benzenesulfonic acid and hydrogen chloride(SRC). The rate constant for the vapor phase reaction of benzenesulfonyl chloride with photochemically produced hydroxyl radicals has been estimated to be 2.04X10-12 cu cm/molecule-sec at 25 °C which corresponds to an atmospheric half-life of 7.9 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm (2,SRC). Direct photolysis is not expected to be a significant removal process since the compound absorbs very little light at wavelengths above 290 nm(3). |

용도
Benzenesulfonyl chloride reacts with Grignard reagents to form oxindoles from N-unsubstituted indoles. It is widely used to check the assay of thiamine in different food products. It is involved in the synthesis of alpha-disulfones, sulfonamides and sulfoante esters as precursor. It is a derivatization reagent for the determination of various amines in waste water and surface water at the sub-ppb level by gas chromatography-mass spectrometry. It is common reagent used in Hinsberg test for detection and distinguishing the type of amines as primary, secondary and tertiary amines.
일반 설명
A colorless to slightly yellow solid that melts at approximately 40°F. Very irritating to skin, eyes and mucous membranes. May emit toxic fumes when heated to high temperatures. Used to make dyes and other chemicals.
제조 및 합성 방법
생산 방법
The most convenient method for the production of benzenesulfonyl chlorides is the chlorosulfonation reaction of benzene or substituted benzene with chlorosulfuric acid. Sulfonation and formation of the sulfonyl chlo- ride take place in one reaction sequence:Ar-H+Cl-SO3H→ArSO3H+HClArSO3H+Cl-SO3H=ArSO2Cl+H2SO4Sulfone is formed in a side reaction of the chlorosulfonation. The amount of sulfone formation can be reduced by diluting with a solvent, by using a large excess of chlorosulfuric acid, or by adding sulfone-inhibiting substances, e.g., alkali metal and ammonium salts, acetic acid, phosphoric acid, dimethylformamide, or amidosulfuric acid.For industrial chlorosulfonation the chlorosulfuric acid is introduced into a cast-steel or enameled steel vessel and 10 – 25 mol% of the aromatic compound is stirred in at 25 – 30 ℃, whereupon sulfonation of the aromatic compound and HCl formation occur. The formation of sulfonyl chloride is initiated by heating the reactants to 50 – 80 ℃. The reaction is exothermic. The sulfonyl chloride is isolated by draining the reaction mass onto water and simultaneous cooling. Excess chlorosulfuric acid is decomposed, and the sulfonyl chloride either precipitates or separates as an organic liquid phase. The quality of the chlorosulfuric acid affects the yield.Other chlorinating agents, such as phosgene, thionyl chloride, sulfuryl chloride, or phosphorus pentachloride, can be used instead of chlorosulfu- ricacid. When thionyl chloride is used the sulfonyl chloride is obtained from the sulfonic acid in high yield and without formation of sulfuric acid.
