摘要： Acetaldehyde oxime, a commercially useful intermediate in the production of pesticides, is prepared by oximating acetaldehyde with an aqueous hydroxylamine-containing solution to form an aqueous oximation reaction mixture and recovering acetaldehyde oxime from the aqueous oximation reaction mixture by distilling a mixture of acetaldehyde oxime and water directly from the aqueous oximation reaction mixture.

摘要： In the halogenation under reflux conditions of an unhalogenated aldehyde of the formula ##STR1## with Cl.sub.2, Br.sub.2 or I.sub.2, the aldehyde and halogen are continuously fed into a reactor at a molar ratio of halogen to unhalogenated aldehyde between about 0.8:1 and about 1.1:1 and water is continuously fed into the unhalogenated reactor at a rate of between about 1% and about 20% by weight of aldehyde. The product .alpha.-haloaldehyde is thiohydrocarbylated and then oximated to form a 2-hydrocarbylthioaldoxime of the formula ##STR2## with improved yield and quality because of the improved yield and quality of unhalogenated .alpha.-haloaldehyde. An exemplary process includes the chlorination of isobutyraldehyde (IBA) to form .alpha.-chloroisobutyraldehyde (CIBA), the thiomethylation of CIBA to form 2-methyl-2 methylthio-propionaldehyde (MTIBA) and the oximation of MTIBA to form 2-methylthio-propionaldehyde oxime (aldicarb oxime or ADO).

C. for a time sufficient to form a vapor stream comprising hexafluoropropylene oxide substantially-free of oxygen; (b) directly contacting said vapor stream, in a catalyst zone, B, containing a fluorinated catalyst which is preferably the same as used in catalyst zone, A, at a temperature of about 400.degree.-650.degree., preferably about 500.degree.-650.degree.

摘要： A mixture of ketoxime such as methyl ethyl ketone oxime (MEKO), an inorganic acid such as sulfuric acid and optionally water is fed to an intermediate point of a fractional distillation column. Steam is fed to the base of the column and operating conditions are sufficient to produce the corresponding ketone (e.g. methyl ethyl ketone) or its water azeotrope as the overhead product and the corresponding hydroxylammonium salt (e.g. the sulfate) as the bottoms. Crystallization of the salt from the bottoms leaves a mother liquor which may be recycled to a reboiler from which the steam is generated.

摘要： An improved process for preparing formaldoxime trimer is provided in which loss of the product is minimized and the prior art problems of long retention times to afford precipitation of the trimer which is difficult to filter and which occludes the undesirable salt of the acid that is difficult to remove. The method disclosed involved oximation of paraformaldehyde using dehydroxylamine sulfate and ammonia gas followed by steam stripping to recover formaldoxime and separate trimerization thereof followed by filtration recovery and drying.The formaldoxime trimer is produced in essentially quantitative yield and proceeds specifically by a procedure of steam stripping out the formaldoxime monomer from the synthesis liquor and allowing separate trimer formation and recovery. The product is free from inorganic salts and the mother liquor with formaldoxime monomer content, resulting from its recovery by filtration, does not represent a yield loss in that it is recyclable to the next synthesis reaction.

摘要： Crude hexafluoroacetone containing as impurities nitrogen oxides and sulfur dioxide is purified by admixing with water to form an aqueous solution, admixing the aqueous solution with concentrated sulfuric acid or oleum to form a vapor and scrubbing the vapor with liquid concentrated sulfuric acid to produce purified anhydrous hexafluoroacetone. The sulfur dioxide and nitrogen oxides interact with the aqueous solution and concentrated sulfuric acid so as not to be found in the purified product, thus obviating the need for a neutralization step.
