suzuki reaction

Strongly irritates skin. Contact may destroy or irreversibly alter skin tissue. Very toxic by ingestion, inhalation, or by skin absorption. Combustible, though may be difficult to ignite.

Fumes in moist air to form hydrogen chloride. Reacts with water to form hydrochloric acid, reaction may be violent.

METHYLPHOSPHONIC DICHLORIDE is incompatible with water, strong oxidizing agents, alcohols, bases (including amines).. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

Poisonous if inhaled or swallowed. Contact causes severe burns to skin and eyes.

METHYLPHOSPHONIC DICHLORIDE may burn but does not ignite readily. May ignite other combustible materials (wood, paper, oil, etc.). Reacts violently with water. Flammable poisonous gases may accumulate in tanks and hopper cars. Runoff to sewer may create fire or explosion hazard. Contact causes severe burns to skin and eyes. Runoff from fire control or dilution water may cause pollution. Violent reaction with water.

Highly flammable; mists or Vapors may form explosive mixture with air. Reacts with moist air forming fumes of hydrogen chloride; may spontaneously ignite. Reacts with water or alcohol, forming hydrochloric acid. The reaction may be violent and ignite unreacted material. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, amines, ethers. May react violently, possibly explosively, when mixed with ethers and trace amounts of metal salts.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water or milk. Do not induce vomiting. Keep victim quiet and maintain normal body temperature. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. Personal Protective Methods: Wear protective eye protection, gloves, and clothing to prevent any reasonable probability of skin or eye contact. Safety equipment suppliers/ manufacturers can provide recommendations on the most protective glove/clothing material for your operation. All protective clothing (suits, gloves, footwear, headgear) should be clean, available each day, and put on before work. Contact lenses should not be worn when working with this chemical. Wear dust-proof chemical goggles and face shield unless full facepiece respiratory protection is worn. Employees should wash immediately with soap when skin is wet or contaminated. Provide emergency showers and eyewash.

UN9206 Methyl phosphonic dichloride, Hazard class: 6.1; Labels: 6.1-Poisonous materials, 8-Corrosive material. Domestic (United States), Inhalation Hazard Zone B. UN3390 Toxic by inhalation liquid, corrosive, n.o.s. with an LC50 # 1000 mL/m3 and saturated vapor concentration ≥ 10 LC50 Hazard Class: 6.1; Labels: 6.1- Poisonous materials, 8-Corrosive material, Technical Name Required, Inhalation Hazard Zone B

Methyl phosphonic dichloride is a low meltingsolid or colorless liquid. Molecular weight = 132.91;Boiling point = 162℃; Freezing/Melting point 5 32℃;Flash point = $ 50℃ (oc). Mixes violently with water.Potential Exposure: Used as a chemical intermediate inpesticide manufacture

Use a licensed professional waste disposal service to dispose of this material. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed

The oxidation of lowvalency organophosphorus compounds is important mainly in the case of the thiophosphonic acid chlorides. This method is used in the production of methylphosphonic acid dichloride by reaction of methyldichlorophosphine with sulfuryl chloride or chlorosulfuric acid. Elemental sulfur reacts with MePCl2 in the presence of catalytic quantities of tetraalkylphosphonium salts to form methylthiophosphonic acid dichloride.

Color Code—White: Corrosive or Contact Hazard;Store separately in a corrosion-resistant location. Prior toworking with this chemical you should be trained on itsproper handling and storage. Store in tightly closed containers in a cool, well-ventilated area. Sources of ignition, suchas smoking and open flames, are prohibited where thischemical is handled, used, or stored. Use only nonsparkingtools and equipment, especially when opening and closingcontainers of this chemical. Wherever this chemical is used,handled, manufactured, or stored, use explosion-proof electrical equipment and fittings
