Reactivity AlertsHighly Flammable
Reactivity ProfileIsocyanates and thioisocyanates, such as METHOXYMETHYL ISOCYANATE, are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence, [Wischmeyer(1969)].
DOT Hazard ClassificationMethoxymethyl isocyanateUN2605Div 6.1 Poisonous materials (49 eCFR § 173.132)PG I: the degree of danger presented by the material is greatSymbol +: Fixes the proper shipping name, hazard class and packing group for that entry
Air and Water ReactionsHighly flammable. Soluble in water.
BrandbekämpfungExcerpt from ERG Guide 155 [Substances - Toxic and/or Corrosive (Flammable / Water-Sensitive)]:
Freisetungsmaßnahmen· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.
Erste HilfeExcerpt from ERG Guide 155 [Substances - Toxic and/or Corrosive (Flammable / Water-Sensitive)]:General First Aid:
Expositionsschutz und Persönliche Schutzausrüstung· Wear positive pressure self-contained breathing apparatus (SCBA).TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].
