Ka ts'ebetso ea eona ea optical, L (+) -Tartaric acid e sebelisoa e le moemeli oa ho rarolla lik'hemik'hale ho rarolla DL-amino-butanol, e leng bohareng ba lithethefatsi tse thibelang lefuba. 'Me e sebelisoa e le letamo la chiral ho kopanya lihlahisoa tsa tartrate. Ka acidity ea eona, e sebelisoa e le sesosa sa ho phethoa ha resin ea lesela la polyester kapa molaoli oa boleng ba pH tlhahiso ea oryzanol. Ka ho rarahana ha eona, L(+) -Tartaric acid e sebelisoa ho electroplating, ho tlosa sebabole le ho khetha acid. E boetse e sebelisoa e le sesebelisoa sa ho kopanya, ho hlahloba li-additives tsa lijo kapa chelating agent tlhahlobong ea lik'hemik'hale le tlhahlobo ea meriana, kapa e le moemeli oa ho daea. Ka phokotso ea eona, e sebelisoa e le ntho e fokotsang ho etsa seipone ka lik'hemik'hale kapa ho nka litšoantšo ho nka lifoto. E ka boela ea rarahane ka ion ea tšepe 'me e ka sebelisoa e le sesebelisoa sa ho hloekisa kapa ho hloekisa holim'a tšepe.
