Abstract: Rearrangement of allyl acetals to ketene acetals is disclosed. The rearrangement is accomplished by mixing the allyl acetal with a solution of an alkali metal lower alkyl in a water-soluble primary amine. After several hours contact with the allyl acetal with the solution ketene acetal formed during the contact is separated from the reaction mixture.

Abstract: Trioxane and other acetals are purified by contacting with an alkali metal superoxide, then isolated in a purified form. Optionally, a phase transfer catalyst can be utilized in the purification. Recovered acetals are sufficiently pure for polymerization to high molecular weight.

Abstract: A process for producing 3,3,7-trimethyl-2,9-dioxatricyclo[3.3.1.0.sup.4,7 ]nonane useful as an insect pheromone and having the formula, ##STR1## which comprises reducing 1,5,5-trimethyl-7-endo-tert-butyldimethylsilyloxy-4-oxabicyclo[4.2.0]octan -3-one with diisobutylaluminum hydride, and treating with an acid, after desilylation.

Abstract: Cyclic oligomers are extracted from liquid polyethers, especially polymers of epihalohydrin, by contacting the polyethers with a hydrocarbon solvent containing 3 to 8 carbon atoms while agitating the polyethers.

Abstract: A process for selectively controlling or interfering with the effect or function of foreign nucleic acid in the presence of otherwise normal living cells which comprises determining the base sequence for the nucleic acid and binding the nucleic acid with an appropriately prepared nonionic oligonucleoside alkyl or arylphosphonate analogue which is complementary to the indicated sequence of the foreign nucleic acid.

Abstract: The present invention is directed to 1-benzoyl-3-(arylpyridyl)urea compounds useful as insecticides.

Abstract: Esters of monoacetals of pentaerythritol. The monoacetals result from the reaction of a 4-hydroxyphenylpropionaldehyde and pentaerythritol, and the further reaction of this monoacetal with either of two particular acid chlorides yields the esters of the invention. These esters are useful, in small proportions, to stabilize polymer compositions, especially olefin polymers.

Abstract: Disclosed herein is a novel 2,3-dialkoxypropyl glyceryl ether and the preparation process for it. The above diglycerin dialkyl ether is readily prepared with high yield and purity by reacting its corresponding glycidyl ether with a protected glycerin to form a 1,3-dioxolan compound, followed by etherifying the thus formed 1,3-dioxolan compound into a dialkyl ether dioxolan compound, and then hydrolyzing the resultant dialkyl ether dioxolan compound. This diglycerin dialkyl ether is useful as an emulsifier, cleaner etc., and is preferably used as a component of cosmetic compositions. A cosmetic composition comprising the above 2,3-dialkoxypropyl glyceryl ether is also disclosed.
