Safety shower and eye bath. Mechanical exhaust required.
GENERAL HYGIENE MEASURES
Wash thoroughly after handling.
PERSONAL PROTECTIVE EQUIPMENT
Respiratory Protection: Use respirators and components tested and

  excess iodine, however, these aliphatic sulfur compounds are converted eventually to the corresponding alkyl iodides. The relative reactivities of these sulfonyl derivatives in the reaction with the triphenylphosphine–iodine system are the following. Aromatic series: ArSO2Cl, ArSO2SAr′>ArSO2H>ArSO3R>ArSO3−HNBu3+ (or PyH+)>ArSO3H>ArSO2SO2Ar>>ArSO2CH2C(CH3)3, ArSO3Ar′. Aliphatic series: RSO2Cl, RSO2SR′,

  通过用三苯基膦和催化量的碘的混合物处理，芳烃磺酸、它们的钠盐和烷基芳烃磺酸盐可以很容易地还原成相应的芳烃硫醇，而烷烃磺酸、亚磺酸、二硫化物、硫代磺酸测试剂和磺酸盐也很容易类似地还原为相应的硫醇。然而，在用三苯基膦和过量碘的混合物处理后，这些脂肪族硫化合物最终转化为相应的烷基碘。这些磺酰基衍生物在与三苯基膦-碘体系反应中的相对反应性如下。芳族系列​​：ArSO2Cl、ArSO2SAr′>ArSO2H>ArSO3R>ArSO3−HNBu3+（或PyH+）>ArSO3H>ArSO2SO2Ar>>ArSO2CH2C(CH3)3、ArSO3Ar′。脂肪族系列：RSO2Cl、RSO2SR'、RSO2-HNBu3+>RSO3-HNBu3+>RSSR，RSO2H>RSO3H>RSH>RSO3R'。在这些反应中，带有供电子取代基的芳烃磺酸比具有供电子取代基的芳烃磺酸更容易被还原。
