摘要:A catalyst for synthesis of lactic acid and it derivatives is provided. The catalyst includes SnY2.mH 2 O and at least one of NH 4 X or quaternary ammonium salts, wherein X and Y are selected from F—, Cl—, Br—, I—, CH 3 SO 3 —, C 6 H 5 SO 3 —, CH 3 C 6 H 4 SO 3 — or CN—, m represents an integer of 1 to 15. A method for synthesis of lactic acid and it derivatives with the above catalyst is also provided. By using the above catalyst and method, it is capable of converting carbohydrate-containing raw material to lactic acid and its derivatives directly in a more efficient and economical way.

标题:Synthesis of stable, water-soluble chemiluminescent 1,2-dioxetanes and intermediates therefor
发明人：BRONSTEIN IRENA Y; EDWARDS BROOKS
权利人:TROPIX INC
摘要:A novel synthesis of 1,2-dioxetane phosphate alkali metal salts and novel intermediates employed in this synthesis are disclosed. A hydroxyaryl enol ether alkali metal salt having the formula: ##STR1## wherein T can be an unsubstituted or substituted adamant-2'-ylidene group, R 3 can be a methyl group, Y can be a phenyl group and M + can be a sodium cation, is reacted with a phosphorohalidate to give the corresponding enol ether ethylene phosphate, which is then reacted with an alkali metal cyanide to give the corresponding enol ether cyanoethyl phosphate diester alkali metal salt intermediate. Singlet oxygen addition to this enol ether cyanoethyl phosphate diester alkali metal salt intermediate to give the corresponding 1,2-dioxetane cyanoethyl phosphate diester alkali metal salt, followed by β-elimination of the cyanoethyl group using an alkali metal hydroxide or the like, gives the corresponding 1,2-dioxetane phosphate alkali metal salt.
