Abstract:
2,6,6-Trimethyl-cyclohex-2-en-1-one is manufactured by reacting ethyl isopropyl ketone with acrolein in an organic solvent in the presence of a strong organic acid at from 40.degree. to 150.degree. C.
Abstract:
A process for recovery of hexafluoroacetone from the hexafluoroacetone-HF complex by contacting the complex with acetic anhydride under reaction conditions. The reaction produces liberated hexafluoroacetone and by-products, acetyl fluoride and acetic acid. The by-products can be further reacted in a cyclic process whereby acetic anhydride is regenerated for recycle.
Abstract:
A process for preparing 2-cis,6-trans-10,11-epoxy-6-ethyl-3,11-dimethyl-2,6-tridecadien derivatives and mixtures of said 2-cis,6-trans-tridecadienn derivatives with its corresponding 2-trans,6-trans-geometric isomers which are useful in killing and preventing proliferation of insects, by upsetting their hormone balance including intermediates in this process.
Abstract:
A process for purifying aromatic ketones from admixture with difficultly separable aromatic acid and alcohol derivatives of said ketone by distillation in the presence of a catalytic amount of a mineral acid.
Abstract:
PRIMARY AMINES ARE RECOVERED FROM THE PRODUCTS OF REDUCTIVE AMINATION OF ALCOHOLS BY CONVERTING THE UNREACTED ALCOHOLS TO ALKYL BORATES AND DISTILLING THE AMINES. PRIMARY AMINES HAVE MANY USES IN COMMERCE, FOR EXAMPLE, THEY ARE USEFUL AS CORROSION INHIBITORS, ORE FLOTATION AGENTS, GERMICIDES, RUBBER MOLD RELEASE AGENTS, PIGMENT COATING AGENTS AND CHEMICAL INTERMEDIATES.
