Abstract: Manufacture of alkene from alkane, said alkene of an equal number of carbons as its alkane precursor, comprising contacting alkane with oxygen in the presence of a boric acid at an elevated temperature, spearating the resultant alkylborate esters from the reaction product, pyrolyzing said alkylborates in an inert atmosphere, preferably in the presence of a methanol or trimethylborate and recovering the formed alkene from the pyrolysis mixture, said recovery preferably including contacting said formed alkene with silica gel.

Abstract: A METHOD OF OXIDIZING N-PARAFFINS OF BETWEEN ABOUT 6 AND 20 CARBONS HAVING AN ULTRAVIOLET LIGHT ABSORBANCY OF AT LEAST ABOUT 1 AT 260-280 MU TO PRODUCE OXIDATES RICH IN SECONDARY ALKANOLS COMPRISING CONTACTING SAID N-PARAFFIN WITH OXYGEN IN THE PRESENCE OF BETWEEN ABOUT .001 AND 5 WT. PERCENT OF PEROXIDE SELECTED FROM THE GROUP CONSISTING OF T-BUTYL HYDROPEROXIDE AND DI-T-BUTYL PEROXIDE AND BETWEEN ABOUT 1 AND 15WT. PERCENT OF A BORON COMPOUND SELECTED FROM THE GROUP CONSISTING OF BORIC OXIDE, BORIC ACID AND ALKYL METABORATE OF BETWEEN ABOUT 3 AND 15 CARBONS, SAID WT. PERCENT BASED ON SAID N-PARAFFIN.

Abstract: A METHOD OF PRODUCING AN EPOXIDE OF THE FORMULA:

2-R1,2-R2,3-R3,3-R4-OXIRANE OR 2,3-(-R5-)OXIRANE

WHERE R1, R2, R3 AND R4 ARE HYDROGEN OR HYDROCARBYL AND R5 IS X,$-ALKYLENE, COMPRISING CONTACTING A FIRST OLEFIN OF THE FORMULA:

R1-C(-R2)=C(-R3)-R4 OR R5
WHERE R THROUGH R5 IS AS HERETOFORE DEFINED WITH A HYDROPEROXY ALKANOATE OF THE FORMULA:

R6-C(-R7)(-O-OH)-OOC-R10 AND/OR R8-C(-R9)(-O-OH)-OOC-R10

WHERE R6, R7, R8 AND R9 ARE HYDROGEN OR HYDROCARBYL AND R10 IS ALKYL OF FROM 1 TO 20 CARBONS IN THE PRESENCE OF A MOLYBDENUM TUNGSTEN OR VANADIUM EPOXIDE PRODUCING CATALYST, SAID ALKANOATE PREPARED BY CONTACTING WITH OZONE A MIXTURE OF SECOND OLEFIN OF THE FORMULA:

R6R7C=CR8R9

WHERE R6, R7, R8 AND R9 ARE AS HERETOFORE DEFINED WITH AN ALKANOIC ACID OF THE FORMULA R10COOH WHERE R10 IS AS HERETOFORE DEFINED.
