Phosgene - COCl2 is used in organic synthesis, in manufacture of dyes, pharmaceuticals, herbicides, insecticides, synthetic foams, resins, and polymers.

Phosgene is a lung irritant and extremely toxic. It is also produced in the presence of refrigerants that are drawn through a heat source, refrigeration technicians should take extreme caution and prevent the exposure by making sure that smoking is avoided in the presence of refrigerants and preventing inhalation of the gas when soldering or brazing.
Also called CARBONYL CHLORIDE, a colourless, chemically reactive, highly toxic gas having an odour like that of musty hay, used in making organic chemicals, dyestuffs, polycarbonate
resins, and isocyanates for making polyurethane resins. It first came into prominence during World War I, when it was used, either alone or mixed with chlorine, against troops. Inhalation
causes severe lung injury, the full effects appearing several hours after exposure.

You ask WAAY too much about lithium compounds. Sounds like you are trying to get a recipe for Crystal Meth and get answers to your homework at the same time. The PROBLEM with modern chemists, scientists, etc. is that they don't 'think' No wonder we can't figure out a more advanced way to fuel vehicles, lazy bums like you waltz through college expecting a handout all the tijme. Gimme money, gimme answers, heck do my term papers while you're at it also ... Guys like you make me sick. Get off your lazy rear and find a solution on you own, without partying with a bunch of frat losers for 3 straight weeks and then stressing over WHY you can't get this done ... College isn't a 4 year beer party, you know, it is a TIME and PLACE of LEARNING (Who'd have thunk it?). If you are still in high-school, then just wake the ^&*( up, and do your own danged homework like 'trance' said ... Vote for me, I want 10 points. (Hey if you can get a handout for everything, why can't I?) - don't be a SlacKeR ...
