Editing Methyl isocyanate (section)

== Physical properties ==
Methyl isocyanate is a colorless, poisonous, [[Lachrymatory agent|lachrymatory]] ([[Tears|tearing]] agent), flammable liquid.<ref name="Union Carbide 1967">Union Carbide Corporation "Methyl Isocyanate" Product Information Publication, F-41443, November 1967.</ref> It is soluble in water to 6–10 parts per 100 parts, but it also reacts with water (see [[#Reactions|Reactions]] below).

It has a refractive index of 1.363 with a wavelength of 589&nbsp;nm at a temperature of 20&nbsp;°C <!--needs atmospheric pressure and medium (e.g. liquid, gas, solid and type of each or reference value by which this refractiveindex and wavelength is calculated --><ref>{{cite journal |last1=Kirilin |first1=Aleksei |last2=Belova |first2=Liya |last3=Pletneva |first3=Maria |title=New aspects of isocyanate synthesis with the use of O-silylurethanes |journal=Mendeleev Communications |date=January–February 2017 |volume=27 |issue=1 |pages=99–100 |doi=10.1016/j.mencom.2017.01.033}}</ref>
