Kopo:

Methyl ethyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) ke motsoako oa tlhaho oa chefo e batlang e le tlase, e fumanoang lits'ebetsong tse ngata. E sebelisoa lihlahisoa tsa indasteri le tsa khoebo e le mokelikeli oa sekhomaretsi, lipente, le lisebelisoa tsa ho hloekisa hape e le sehlapi sa de-waxing. Karolo ea tlhaho ea lijo tse ling, methyl ethyl ketone e ka lokolloa tikolohong ke libaka tse foqohang seretse se chesang le mello ea meru. E boetse e sebelisoa e le monko o monate lijong.

MEK e sebelisoa e le solvent bakeng sa lisebelisoa tse fapaneng tsa ho roala, mohlala, vinyl, li-adhesives, nitrocellulose, le liphahlo tsa acrylic. E sebelisoa ho tlosa pente, li-lacquers, li-varnish, lipente tsa spray, sealers, glues, litheipi tsa makenete, li-inks tsa khatiso, li-resin, rosin, litharollo tsa ho hloekisa le ho etsa polymerization. E fumanoa lihlahisoa tse ling tsa bareki, mohlala, samente tsa malapa le tsa ho itlosa bolutu, le lihlahisoa tsa ho tlatsa lehong. MEK e sebelisoa ho tlotsa oli e tlotsang, ho theola litšepe, tlhahiso ea matlalo a maiketsetso, pampiri e pepeneneng le foil ea aluminium, hape e le lik'hemik'hale tse mahareng le tse thusang. Ke sehlapolli sa ho ntša lijo ha ho etsoa lijo le metsoako ea lijo. MEK e ka boela ea sebelisoa ho thibela lisebelisoa tsa ho buoa le tsa meno.
Ntle le tlhahiso ea eona, mehloli ea tikoloho ea MEK e kenyelletsa mosi o tsoang ho jete le lienjineri tse tukang ka hare, le mesebetsi ea indasteri e kang khase ea mashala. E fumanoa ka bongata mosi oa koae. MEK e hlahisoa ka biologically mme e khethiloe e le sehlahisoa sa metabolism ea likokoana-hloko. E boetse e fumanoe limela, li-pheromone tsa likokoanyana, le lisele tsa liphoofolo, 'me MEK mohlomong ke sehlahisoa se senyenyane sa metabolism e tloaelehileng ea mammalian. E tsitsitse tlas'a maemo a tloaelehileng empa e ka etsa peroxides polokelong ea nako e telele; tsena li ka 'na tsa phatloha.
