Boiling Point:70.5 °C
Flash Point:-16.1±0.0 °C
Refractive Index:1.410
Water Solubility:reacts
Storage Conditions:Dimethyldichlorosilane must be stored to avoid contact with oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates) since violent reactions occur. Before entering confined space where this chemical may be present, check to make sure that an explosive concentration does not exist. Store in tightly closed containers in a cool, well-ventilated area away from water, steam, or moisture because toxic and corrosive hydrogen chloride gas can be produced. Do not store at tempe
Vapor Pressure:<200 hPa (20 °C)
Vapor Density:Relative vapour density (air = 1): 4.4
Toxicity:LD50 orally in Rabbit: 6056 mg/kg
Flammability characteristics:Lower flammable limit: 3.4%; Upper flammable limit: 9.5%
Explosive limit:Explosive limits , vol% in air: 1.4-9.5
Odor:SHARP, LIKE HYDROCHLORIC ACID
Henrys Law Constant:Henry's Law constant = 1.8X10-2 atm-cu m/mol at 25 °C (est)
Experimental Properties:Reacts with water to form complex mixture of dimethylsiloxanes, and liberates hydrogen chloride.|Freezing point: -86 °C|Organo-functional silanes are noted for their ability to bond organic polymer systems to inorganic substrates. /Silane cmpd/|The reaction of organosilanes with halogens and halogen cmpd usually proceeds in good yield through cleavage of the Si--H bond and formation of the silicon-halogen bond. Reaction with fluorine, however, does not proceed satisfactorily because of cleavage of not only the Si--H but also C--Si and C--H bonds. Direct halogenation with chlorination, bromine, and iodine proceeds smoothly, however. /Organosilanes/|Hydroxyl radical reaction rate constant = 2.9X10-13 cu cm/molec-sec at 25 °C (est)
Air and Water Reactions:Highly flammable. Fumes in air. May react violently with water (moisture in air or soil) to generate hydrogen chloride, Title 46(1966). Dimethyldichlorosilane reacts vigorously with water to generate gaseous HCl. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Chloride gas will be created in 0.75 minutes. Experimental details are in the following: "Development of the Table of Initial Isolation and Protective Distances for the 2008 Emergency Response Guidebook", ANL/DIS-09-2, D.F. Brown, H.M. Hartmann, W.A. Freeman, and W.D. Haney, Argonne National Laboratory, Argonne, Illinois, June 2009.
Reactive Group:Chlorosilanes
Reactivity Alerts:Highly Flammable
Reactivity Profile:Chlorosilanes, such as DIMETHYLDICHLOROSILANE, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases.
Autoignition Temperature:750 °F (USCG, 1999)|716 °F (380 °C)|380 °C
Flammable Limits:Lower flammable limit: 3.4%; Upper flammable limit: 9.5%
Physical Dangers:The vapour is heavier than air and may travel along the ground; distant ignition possible.
Corrosivity:Corrosive
Heat of Vaporization:100 BTU/LB = 58 CAL/G = 2.4X10+5 JOULE/KG

Handling and StoragePrecautions for safe handling
NO open flames, NO sparks and NO smoking. NO contact with hot surfaces. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Fireproof. Separated from incompatible materials. See Chemical Dangers. Cool. Dry. Keep under inert gas. Well closed.SRP: Operations involving entry into tanks or closed vessels, and emergency situations, require consideration of potentially oxygen deficient, or "immediately dangerous to life and health" IDLH environments. This may necessitate use of a self-contained breathing apparatus (SCBA), or a positive pressure supplied air respirator.
