on this compound.
|Use|| AS LAB REAGENT
NO LONGER USED FOR CHLOROMETHYLATION IN INDUSTRY, BUT IS USED AS
THE MONITORING INDICATOR FOR CHLOROMETHYL ETHER, BECAUSE OF ITS
GREATER STABILITY IN WORKROOM AIR, AND AS AN INT IN SYNTHESIS OF/
ANIONIC EXCHANGE STRONG-BASE RESINS OF THE QUATERNARY AMMONIUM
This cmpd is used as an alkylating agent in the manufacture of polymers.
|Apparent Color|| COLORLESS LIQUID
|Odor|| Suffocating odor
|Boiling Point|| 106 DEG C
|Melting Point|| -41.5 DEG C
|Molecular Weight|| 114.97
|Density|| 1.323 @ 15 DEG C/4 DEG C
|Sensitivity Data|| VAPOR IS STRONG IRRITANT TO EYES, RESPIRATORY TRACT.
Harmful effects and symptoms: Local vapor is severely irritating to the skin and mucous
Bis(chloromethyl) ether has an extremely suffocating odor even in minimal concentrations so that
experience with acute poisoning is not available. It is not considered a respiratory irritant at concn
of 10 ppm.
|Environmental Impact|| Bis(chloromethyl) ether (BCME) might possibly enter the atmosphere in exhaust gases
associated with the use of chloromethyl methyl ether in which BCME is a contaminant and as a
chemical intermediate or in situations where it may be formed from hydrochloric acid and
formaldehyde in the atmosphere. Due to its rapid rate of hydrolysis (half-life < 1 min), BCME
would not be expected to persist in water. It is, however, relatively stable in air (estimated half-life
< 1 day for photooxidation and > 18 hr for hydrolysis) and may therefore be an occupational
contaminant if it escapes in exhaust gases or is formed in the work place.
|Environmental Fate|| TERRESTRIAL FATE: The fate of bis(chloromethyl) ether in soil is unknown. However
due to its rapid hydrolysis it would be expected to disappear rapidly from moist soil.
AQUATIC FATE: Bis(chloromethyl) ether will rapidly disappear from any aquatic system by
hydrolysis (half-life 10-38 sec)(1,2). The decomposition products are HCI and formaldehyde .
ATMOSPHERIC FATE: The hydrolysis half-life of bis(chloromethyl) ether (BCME) in humid air
is > 18 hr(1,2). However it is estimated that BCME will degrade by reaction with photochemically
produced hydroxyl radicals (half-life < 4.1 day).
