A process for preparing hydroxy phosphonic acid ester polyols by reacting an alkenyl phosphonic acid with an alkylene oxide and the reaction of the resulting hydroxy phosphonic acid ester polyols with polyisocyanates to form polyurethanes is described.

Alkylene phosphonate acid ester polyols

A method of producing methyl formate from methanol and carbon monoxide using an anionic transition metal catalyst including a metal selected from Fe, Ru, Os, W, Mo, Cr, Co, Rh and Ir. The reaction is characterized as a low pressure reaction conducted at a pressure less than 3,000 psia and using concentrated anhydrous methanol solutions and, preferably neat methanol. The catalyst can be a mixed metal catalyst including a second metal selected from Group VIII metals. The reaction is highly selective towards methyl formate and excellent turnover numbers are obtained using these catalysts.

A process for preparing menthane diisocyanate by reaction of a terpinyl monoisocyanate with isocyanic acid in a medium which is an excess of isocyanic acid, a polar solvent, or a mixture of solvents which includes a polar solvent in the presence of a catalyst which is a Bronsted acid or a Lewis acid is disclosed.

A method of reactivating anionic Group VIII hydroformylation catalysts to maintain high selectivity towards linear products. In the process of manufacturing aldehydes and alcohols from olefins, hydrogen, carbon monoxide and a catalyst, the selectivity for linear products is extremely high when an anionic Group VIII catalyst is used. This selectivity, after prolonged use of a catalyst, falls off along with the turnover number. The catalyst is reactivated to increase the selectivity towards linear products as well as the turnover number by subjecting the catalyst to a reducing agent which is strong enough under treatment conditions to reduce the anionic Group VIII catalyst. Reactivation of anionic iron, ruthenium, osmium, and mixed transition metal complex catalysts are particularly described and claimed.

Method of reactivating Group VIII anionic hydroformylation catalysts

A process for producing linear aldehydes or alcohols from olefins using a mixed transition metal hydroformylation catalyst wherein the catalyst comprises a mixture of transition metal compounds wherein the first component is an anionic transition metal catalyst having a charge of at least -2. The formula of the anionic compound is generally defined as M.sup.+n [H.sub.y A.sub.x L.sub.z ].sup.-n wherein A represents Fe, Ru, Os, W, Cr, Co, Rh, Ir or Mo, M is a cationic species, n is an integer greater than or equal to 2, x is an integer greater than or equal to 1, y is an integer greater than or equal to 0 and z is an integer generally corresponding to the number of available coordination bonding sites of A. The second component is a Group VIII compound, preferably a halide or carbonyl of the Group VIII compound. These compounds exhibit high selectivity toward linear products.

A process for producing linear aldehydes or alcohols from olefins using a transition metal hydroformylation catalyst wherein the catalyst comprises an anionic transition metal catalyst wherein the transition metal is Fe, Ru or Os and the catalysts generally have a charge of at least -2. The formula of the anionic catalyst is generally defined as M.sup.+n [H.sub.y A.sub.x L.sub.z ].sup.-n wherein A represents Fe, Ru or Os, M is a cationic species, n is an integer greater than or equal to 2, x is an integer greater than or equal to 1, y is an integer greater than or equal to 0 and z is an integer generally corresponding to the number of available coordination bonding sites in the ruthenium complex. Monoanionic osmium catalysts are also included within the present invention. These hydroformylation catalysts exhibit greater selectivity toward straight chained aldehydes and alcohols than anionic catalysts having a charge of -1 or a neutral catalyst. The monoanionic osmium catalyst also exhibits an increased selectivity toward the straight chain product. The novel hydroformylation catalyst of the present invention is also disclosed.
