    Abstract: A PROCESS FOR BROMINATING BUTYNE -(2)-DIOL-(1,4) IN WHICH SAID COMPOUND IS REACTED WITH ELEMENTARY BROMINE IN AN AQUEOUS-MINERAL ACID MEDIUM AT A TEMPERATURE OF -40* C. TO 150* C. THE REACTION CAN TAKE PLACE EITHER IN THE PRESENCE OF CATALYSTS OR IN THE ABSENCE OF CATALYSTS. THE MOLAR RATIO OF BROMINE TO BUTYNE-(2)DIOL-(1,4) USED IN THE REACTION CAN RANGE FROM 1:1 TO 20:1. THE PROCESS IS USED TO PRODUCE 23-DIBROMOBUTENE(2) - DIOL - (1,4), 2,2,3,3 - TETRABROMOBUTANEDIOL-(1,4), MUCOBROMIC ACID OR 2 - HYDROXY -3,3,4,4 - TETRABROMOTETRAHYDROFURAN. THE INVENTION ALSO IS DIRECTED TO THE NOVEL COMPOUND 2 - HYDROXY-3,3,4,4-TETRABROMOTETRAHYDROFURAN.

    Abstract: The invention comprises pyridazones of the formula wherein R1 represents a phenyl or cyclohexyl radical, optionally substituted by a methyl group or halogen atom, and R2 represents a methyl, ethyl or acetyl radical. The compounds are made by reacting an alcoholate with a 1 - substituted - 4,5 - dibromopyridazone - (6) or by reacting an alkyl or acetyl halide with a 1 - substituted - 4 - hydroxy - 5 - bromopyridazone - (6). The compounds are used as herbicides (see Division A5). Specified compounds are 1 - cyclohexyl - 4 - methoxy - , 1 - phenyl - 4 - methoxy -, 1 - phenyl - 4 - ethoxy -, 1 - phenyl - 4 - acetoxy -, and 1 - p - fluoro - phenyl - 4 - methoxy - 5 - bromopyridazones.ALSO:Compounds of the formula wherein R1 represents a phenyl or cyclohexyl radical, optionally substituted by a methyl group or halogen atom, and R2 represents a methyl, ethyl or acetyl group, are used as herbicides, either alone or in admixture with a liquid or solid carrier. The herbicidal compositions may also include wetting agents, emulsifiers, glue, alginates or resins and may be used in conjunction with other active substances such as fertilisers.
