Inclusion of a branched alcohol in the catalytic hydrogenation reaction involving an aliphatic nitro compound dramatically increases the efficiency of the conversion of nitro groups into amino groups. This discovery is of particular value in the production of polyalkyleneamines via nitration of a polyalkene, such as a polybutene, and its subsequent reduction. The polyalkyleneamines so produced are useful as dispersant additives for motor oils and fuels.

Advances in amination

The present invention is directed toward effective photoresist stripping compositions that are less corrosive and do not cause skin irritation. One form of the present invention is a composition useful as a photoresist remover that includes an alkylene carbonate, and one or more additional components chosen from the group that includes alkyl hydrogen peroxides, hydroxyalkyl ureas, urea-hydrogen peroxides, N-substituted morpholines and alcohols. Another form of the present invention is a composition for removing photoresist from a surface that includes an N-substituted morpholine.

Alternative photoresist stripping solutions

This invention concerns a composition comprising a blend of polyolefin with the reaction of a functionalized polyolefin and polyetheramine in which the polyetheramine is grafted into the functionalized polyolefin in a customary mixing apparatus. A process for producing the reaction product of functionalized polypropylene and polyetheramine by melting with polypropylene in a customary mixing apparatus is also disclosed. Blends of the present invention are advantageously useful to prepare paintable automotive body parts. This invention further includes dyeable polyolefin compositions containing the reaction product of functionalized polyolefin and polyetheramine. Dyeable polyolefin fibers, including polypropylene fibers, are disclosed, which may be made by melt spinning, and which may be employed to make woven. and non-woven fabric.

Provided herein are developer solutions useful in producing semiconductor-based circuit elements or precursors thereof, which contain tris-(2-hydroxyethyl)methylammonium hydroxide. Developers according to the invention are either aqueous or alcoholic solutions of tris-(2-hydroxyethyl)methylammonium hydroxide which preferably further comprise a stabilizer. Through use of the compositions provided herein, greatly reduced levels of volatile amines are released during the developing process which lessens the burden on clean room atmosphere purification equipment owing to lessened airborne impurities.

A method is provided for the preparation of tertiary polyamines by alkylating a polyamine having at least two primary amino groups without the use of excess solvent. More particularly, a tertiary amine is produced by reductively alkylating a polyamine with a carbonyl compound, such as formaldehyde, in a reaction zone while in the presence of a hydrogenation catalyst and hydrogen under reductive conditions. The carbonyl compound is continuously supplied to the reaction zone.

Reductive alkylation of polyamines

Synthetic lubricant base stocks having improved properties are disclosed. The base stocks may be obtained by a two-step process, comprising the steps of (1) co-reacting vinylcyclohexene and long-chain linear olefin with a free-radical initiator; and (2) further reacting the mixture resulting from step (1) in the presence of an acidic montmorillonite clay.

Synthetic lubricant base stocks by co-reaction of vinylcyclohexene and

Liquid hydroxyurethane products having cyclocarbonate end groups are prepared by reacting a molar excess of a bis-carbonate of a bis-glycidyl ether of neopentyl glycol or 1,4-cyclohexanedimethanol with a polyoxyalkylenediamine such as a polyoxypropylenediamine. These products are useful for the preparation of polyurethanes, polyurethane polyols, polyester polyurethane polyols, and polycarbonate polyurethane polyols.

Liquification of bis-carbonates of bis-glycidyl ethers

This invention is concerned with a soil stabilization process in which soil particles comprising the soil surfaces to be stabilized are contacted or treated with an aqueous solution of an alkali metal silicate, such as sodium silicate, and a carbonate reactant or gelling agent selected from the group consisting of an alkylene carbonate, such as ethylene carbonate, a polyester polycarbonate and mixtures thereof. This invention also relates to soil stabilized by admixture with (1) an aqueous solution of an alkali metal silicate and (2) the carbonate reactant.
