| 中文摘要 | liquid-liquid reaction of hydrogen peroxide and sodium hypochlorite for the production of singlet oxygen in a centrifugal flow singlet oxygen generator |
| 英文摘要 | an attempt is made to produce gas-phase singlet oxygen o-2(a(1)delta(g)) in a liquid-liquid reaction between acidic hydrogen peroxide (ahp) and sodium hypochlorite (naocl). the attempt arises from the fact that basic hydrogen peroxide (bhp) has long been the prime source for producing singlet delta oxygen through its reaction with chlorine. however, bhp suffers from the defect of being unstable during storage. exploratory experiments were performed in a centrifugal flow singlet oxygen generator (cf-sog) with two streams of solutions, ahp and naocl, mixed in a slit nozzle and then injected into the arc-shaped concavity in the cf-sog to form a rotating liquid flow with a remarkable centrifugal force. with the help of this centrifugal force, the product of the o-2((1)delta) reaction was quickly separated from the liquid phase. the gas-phase o-2((1)delta) was detected via the spectrum of o-2((1)delta) cooperative dimolecular emission with a ccd spectrograph. experimental results show that it is feasible to produce gas-phase o-2((1)delta) from the ahp + naocl reaction, and the stronger the acidity, the more efficient the o-2((1)delta) production. however, since in the ahp + naocl reaction, cl-2 un-avoidably appears as a byproduct, its catalytic action on the decomposition of h2o2 into ground-state o-2 remains a major obstacle to utilising the ahp + naocl reaction in producing gas-phase o-2((1)delta). qualitative interpretation shows that the ahp + naocl reaction is virtually the reaction of interaction of molecular h2o2 with molecular hocl, its mechanism being analogous to that of reaction of bhp with cl-2, where hoocl is the key intermediate. it is difficult to form the intermediate hoocl via the h2o2 + naocl reaction in a basic medium, thus gas-phase o-2((1)delta) cannot be obtained in appreciable quantities. |
