Notes
Other information
Consider storage under inert gas.
for commercial quantities of isocyanates:
·
Isocyanates should be stored in adequately bunded areas. Nothing else should be kept within the same bunding. Pre-polymers need not be
segregated.
Store in original containers.
Keep containers securely sealed.
No smoking, naked lights or ignition sources.
Conditions for safe storage, including any incompatibilities
Suitable container
Metal can or drum
Packaging as recommended by manufacturer.
Check all containers are clearly labelled and free from leaks.
Storage incompatibility
The substance may be or contains a 'metalloid'
The following elements are considered to be metalloids; boron,silicon, germanium, arsenic, antimony, tellurium and (possibly) polonium
The electronegativities and ionisation energies of the metalloids are between those of the metals and nonmetals, so the metalloids exhibit
characteristics of both classes. The reactivity of the metalloids depends on the element with which they are reacting. For example, boron acts as
a nonmetal when reacting with sodium yet as a metal when reacting with fluorine.
Silicas:
react with hydrofluoric acid to produce silicon tetrafluoride gas
react with xenon hexafluoride to produce explosive xenon trioxide
reacts exothermically with oxygen difluoride, and explosively with chlorine trifluoride (these halogenated materials are not commonplace
industrial materials) and other fluorine-containing compounds
may react with fluorine, chlorates
are incompatible with strong oxidisers, manganese trioxide, chlorine trioxide, strong alkalis, metal oxides, concentrated orthophosphoric acid,
vinyl acetate
may react vigorously when heated with alkali carbonates.
Avoid strong acids, bases.
·
Avoid reaction with water, alcohols and detergent solutions. Isocyanates are electrophiles, and as such they are reactive toward a variety of
nucleophiles including alcohols, amines, and even water. Upon treatment with an alcohol, an isocyanate forms a urethane linkage.
A range of exothermic decomposition energies for isocyanates is given as 20-30 kJ/mol.
The relationship between energy of decomposition and processing hazards has been the subject of discussion; it is suggested that values of
energy released per unit of mass, rather than on a molar basis (J/g) be used in the assessment.
For example, in 'open vessel processes' (with man-hole size openings, in an industrial setting), substances with exothermic decomposition
energies below 500 J/g are unlikely to present a danger, whilst those in 'closed vessel processes' (opening is a safety valve or bursting disk)
present some danger where the decomposition energy exceeds 150 J/g.
