Abstract:
The invention provides a method for the reductive amination of diethanolamine to form a product composition that includes piperazine (PIP) and aminoethylethanolamine (AEEA). A catalyst with a transitional alumina/second metal oxide support and a mixture of catalytic metals is used for the reaction which results in low levels of non-PIP and non-AEEA side products.
Abstract:
A heterogeneous procatalyst includes a titanium species, a magnesium chloride component, and a chlorinating agent having a structure A(C)x(R1)3-x, where A is aluminum or boron, R1 is a (C1-C30) hydrocarbyl, and x is 1, 2, or 3. The magnesium chloride component may be thermally treated at a temperature greater than 100 C for at least 30 minutes before or after introduction of the chlorinating agent and titanium species to the heterogeneous procatalyst. The heterogeneous procatalyst having the thermally treated magnesium chloride exhibits improved average molecular weight capability. Processes for producing the heterogeneous procatalyst and processes for producing ethylene-based polymers utilizing the heterogeneous procatalyst are also disclosed.

Abstract:
The present invention discloses a polymeric polyol composition useful for making polyurethane polymers, especially polyurethane foams. Said polyurethane polymer foams demonstrate a good balance of mechanical properties, physical properties, and low emissions. The polymeric polyol composition is the reaction product(s) of (i) a polyamine initiator composition comprising the polymerization product(s) of aminoethylpiperazine with (ii) at least one epoxide compound, at least one glycidyl ether compound, or mixtures thereof.
