摘要:
Disclosed are methods for dissolving biopolymers and synthetic polymers using mixtures of different ionic liquids and compositions comprising the mixture. The methods involve contacting a polymer with a mixture of ionic liquids to provide a composition of polymer and the mixture; the mixture of ionic liquids is prepared by either mixing ionic liquids or by a process comprising reacting ionic liquid precursors in one-pot to form the ionic liquids.

The present disclosure generally pertains to systems and methods for releasing children from child safety seats. A child safety seat is secured to a vehicle seat, and a child is secured to the child safety seat. A single release action enables the child to be removed from the child safety seat thereby facilitating removal of the child from the child safety seat and reducing the time required to remove the child from the child safety seat.

This invention relates to copper-containing organometallic complexes, and to concentrates and diesel fuels containing said complexes. The diesel fuels are useful with diesel engines equipped with exhaust system particulate traps. The copper-containing organometallic complex is used for lowering the ignition temperature of exhaust particles collected in the trap. The copper-containing organometallic complex is soluble or stably dispersible in the diesel fuel and is derived from (i) an organic compound containing at least two functional groups attached to a hydrocarbon linkage, and (ii) a copper-containing metal reactant capable of forming a complex with the organic compound (i). The functional groups are .dbd.X, --XR, --NR., --NO., .dbd.NR, .dbd.NXR, .dbd.N--R*--XR, ##STR1## --CN, --N.dbd.NR or --N.dbd.CR.; wherein X is O or S, R is H or hydrocarbyl, R* is hydrocarbylene or hydrocarbylidene, and a is a number (e.g., zero to about 10). The copper can be combined with one or more metals selected from the group consisting Na, K, Mg, Ca, Sr, Ba, V, Cr, Mo, Fe, Co, Zn, B, Pb, Sb, Ti, Mn and Zr. This invention is also directed to methods of operating a diesel engine equipped with an exhaust system particulate trap using the foregoing diesel fuel.
