A monomer alcohol composition containing a mixture of mono-hydroxymethyl-, dihydroxymethyl-, and trihydroxymethyl-substituted fatty acids and/or fatty acid esters having a diol/triol weight ratio of less than 5/1 and an average functionality number from greater than 0.90 to less than 1.20. The monomer alcohol can be converted into an oligomeric polyol for use in the manufacture of polyurethane flexible foams.
摘要:
Polyurethanes, and rigid polyurethane foams in particular, are made using certain amides of modified fatty acids. The fatty acid groups are substituted hydroxymethyl, N-hydroxyalkyl aminoalkyl or hydroxy-substituted ester groups. The amide portion of the molecule contains hydroxyalkyl or other hydroxyl-substituted organic groups bonded to the amide nitrogen.
摘要:
A non-aqueous hydroformylation process with liquid catalyst recycle involving a hydroformylation step and one or more stages of phase separation to recover a high molecular weight aldehyde product with efficient recovery of rhodium catalyst. The process includes a hydroformylation step to prepare a non-aqueous hydroformylation reaction product composition comprising one or more aldehyde products, one or more conjugated polyolefins, a rhodium-organophosphorus ligand complex, free organophosphorus ligand, and an organic solubilizing agent for said complex and said free ligand, and thereafter one or more stages of phase separation using added water under a carbon monoxide gas, hydrogen gas, or a mixture thereof. The process requires a specific range of total pressure for the hydroformylation, a specific range of total pressure for at least one of the separation stages, and a minimum sum of the total pressure of the hydroformylation step and the total pressure of the separation stage containing said gas.

摘要:
A method of preparing an aromatic phosphine monosulfonate in zwitterionic form, such as dicyclohexylphenylphosphine monosulfonate zwitterion, involving contacting an aromatic phosphine with a sulfonating agent to provide a reaction mixture containing aromatic phosphine monosulfonate in acid form and unconverted sulfonating agent; quenching or removing substantially all of the unconverted sulfonating agent; partially neutralizing the aromatic phosphine monosulfonate in acid form to phase separate aromatic phosphine monosulfonate in zwitterionic form as a solid or neat liquid layer; and collecting the zwitterion as a solid or neat liquid. The zwitterion may be neutralized to form the corresponding aromatic phosphine monosulfonate metal salt, which is useful in preparing catalysts for hydroformylation processes.
