Degradation of paper is retarded by treating paper with melamine. Method of treating existing paper with melamine to stop or retard degradation and methods for inclusion of melamine in paper as made to provide an age resistance paper are described. Rare books, paintings and prints can be preserved or books, paintings and prints as originally formed can use melamine-treated paper to retard degradation.

Method of retarding paper degradation with time by treatment with

Disclosed is a process for recovering a virtually water-free amine from an amine acid salt thereof. The process comprises a unique combination of phase separation stages practiced under mild heating and distillation stages. An amine product containing less than 0.2% water can be achieved by the present process. The feedstock for the process suitably is an acid scrub liquor used to scrub amine from a vapor stream thereof which has been used in a cold-box molding process in the foundry industry or in the cure of vapor permeation curable coatings in the coatings industry.

Process for recovery of amine from spent acid stripping liquor

A process for the production of isobutyryl fluoride by reacting isopropyl fluoride and carbon monoxide in the presence of anhydrous hydrofluoric acid is described.

Preparation of isobutyryl fluoride

A method for catalytically isomerizing a mixture of hexacyclic dimers obtained by dimerizing norbornadiene in the presence of a zero valent iron complex whereby the hydrogenated derivatives of the resultant isomerization product exhibits substantially lower freeze point than that associated with the hydrogenated derivatives of said precursor dimer mixture, the latter representing the highest energy liquid hydrocarbon fuel commercially available.

Method for preparing high density liquid hydrocarbon fuels

A high density fuel composition having low temperature operational capability for propelling turbo-jet, limited volume missile systems consisting essentially of at least 95 weight percent exo-tetrahydrodicyclopentadiene (JP-10) and a correspondingly minor amount of a C.sub.3 -C.sub.7 saturated hydrocarbon.

High density turbine fuel

A process for the production of isobutyric acid anhydride in which propylene is initially carbonylated in the presence of a substantial molar excess of liquid anhydrous hydrogen fluoride to provide a reaction mixture of isobutyroyl fluoride and unreacted hydrogen fluoride. Following distillation of the reaction mixture to recover a recycle stream of hydrogen fluoride, the isobutyroyl fluoride residue is partially hydrolyzed in the presence of a hydrogen fluoride acceptor resulting in a hydrolysis product consisting essentially of isobutyroyl fluoride, isobutyric acid anhydride and a hydrogen fluoride complex of said acceptor. Following removal of the solid complex, the hydrolysis product is fractionally distilled to yield an overhead fraction of isobutyroyl fluoride for reuse in the hydrolysis reaction.

Process for the production of isobutyric acid anhydride

A high density specialty fuel for propelling limited volume ramjet and turbojet missile systems comprising a blend of at least 70 weight percent of exotetrahydrodicyclopentadiene and a correspondingly minor amount of a combination of a C.sub.5 -C.sub.7 alkane or cycloalkane and a tetrahydro derivative of the trimer and/or co-trimer of cyclopentadiene and methylcyclopentadiene.

High density fuel compositions

Method for effecting the formation of co-trimers of cyclopentadiene and methylcyclopentadiene whereby a mixture of the dimers of said dienes is heated in the presence of an inert solvent. The foregoing method is implemented to provide a high energy fuel by substantially completely hydrogenating the resultant trimerization product.

Process for preparing high density fuels

A method for converting endo-tetrahydrodicyclopentadiene to the corresponding exo isomeric form which is advantageously carried out in the presence of aluminum chloride catalyst and the spent nickel hydrogenation catalyst utilized in hydrogenating an endo dimer of cyclopentadiene to provide said tetrahydro derivative thereof.

Production of high energy fuel

Liquid organic reaction products prepared in the presence of homogeneous iron catalyst values are contacted with a strong Lewis acid to effect removal of said values as inorganic precipitates.
