The process for preparing an alkylene oxide adduct, including the steps of feeding an organic compound having active hydrogen and an alkylene oxide to a reaction column packed with a solid catalyst, and carrying out addition reaction of the organic compound having active hydrogen with an alkylene oxide in a gas-liquid fixed bed reaction, wherein the alkylene oxide is in a state of gas and the organic compound having active hydrogen is in a state of liquid.

A polymeric composition may include an isocyanate component and an amine component, which includes: ##STR1## where R.sub.1 represents a hydrocarbon radical, X represents an organic group, and a is an integer. The polymeric composition may further include: ##STR2## where R.sub.2 represents a hydrocarbon radical; Y represents an organic group; and b is an integer. Methods of forming such polymeric and amine compositions and methods of applying such polymeric systems are also provided.

Adducts of low boiling isocyanates with .beta.-diketones which decompose on heating to give the low boiling isocyanates as a condensible vapor; as well as the method of making the adducts and the method of storing and transporting low boiling isocyanates employing said adducts.

The invention provides novel aldehyde adducts of triamterene having improved solubility and bioavailability as compared to triamterene. Pharmaceutical compositions containing the novel adducts and having diuretic activity are also described.

Process for the preparation of organic isocyanates in which a furoxan is heated in the presence of a vicinal diketo compound containing two adjacent keto carbonyl groups. When the furoxan ring is fused to an organic ring system di-isocyanates are produced. An adduct of the furoxan and the diketo compound may be isolated from the reaction mixture and used as a stable isocyanate precursor, for example, a "one-pot" polyurethane composition.

3-Oxopropyl isocyanurate compositions are prepared by addition of acrolein to isocyanuric acid. Reaction of the 3-oxopropyl isocyanurate compositions with alcohols yields hemiacetals and acetals. The compositions and their hemiacetals and acetals are useful polymerizing or crosslinking agents for polyfunctional compounds containing aldehyde-reactive groups.

Adducts of tetrasubstituted pyrophosphato titanates and/or amines, having the formula are useful in improving the physical and chemical properties of many filled resins.

Sodium 6-[D(-)-.alpha.-(4-hydroxy-1,5-naphthyridine-3-carboxamido)phenylacetamido ]penicillanate or its hydroxylated derivative at the p-position of the phenyl group in a crude state can be purified efficiently through its dimethyl sulfoxide adduct.

This invention relates to adducts of tetra-substituted titanates and di-substituted hydrogen phosphites; the use of such adducts for treating particulate fillers, including pigments; the compositions of fillers and the aforesaid adducts with epoxy resins and other casting resins; the reaction product of said adducts with aromatic polyamines; the use of said reaction products for curing epoxide and urethane resins; and compositions of certain of the adducts and casting resins. The titanate-phosph...
