The present invention relates to a metal phase transformation compound and a method for preparing the same.

The present invention discloses a diphenylamine-linked chiral bis(oxazoline) ligand without C.sub.2-symmetry of formula 3 and its synthesis method and application in an asymmetric catalytic reaction, wherein C.sub.2-symmetry is lost by introducing different groups into the diphenylamine backbone to realize precise control of “electronic effect” of the ligand backbone. An anthranilic acid derivative and an orthochlorobenzoic acid derivative are used as starting materials to prepare a compound of formula 1, and then the compound of formula 1 is reacted with a chiral amino alcohol compound to prepare a β-bishydroxy amide compound of formula 2, and the compound of formula 2 is further subjected to condensation to obtain the diphenylamine-linked chiral bis(oxazoline) ligand without C.sub.2-symmetry of formula 3. The present invention also provides an application of a catalyst formed by coordination of the diphenylamine-linked chiral bis(oxazoline) ligand without C.sub.2-symmetry with copper salt, zinc salt, nickel salt, iron salt or rhodium salt, in an asymmetric catalytic reaction.

Disclosed are air-stable small-molecule adsorbents trimeric [Cu—Br].sub.3 and [Cu—H].sub.3 that undergo a reversible solid-state molecular rearrangements to [Cu—Br.(alkene)].sub.2 and [Cu—H.(alkene)].sub.2 dimers. The reversible solid-state rearrangement allows one to break adsorbent design trade-offs and achieve low heat of adsorption while retaining high selectivity and uptake.

Disclosed herein is a process for separating a hydrocarbon feed gas mixture comprising constituents including ethylene to produce a separated ethylene product. The disclosed process employs a solid-state ethylene sorbent and temperature and/or pressure swing adsorption and membrane separation and demonstrates a methodology to reduce the net heat of reaction during the adsorption of ethylene onto an adsorbent.

A light-absorbing composition according to the present invention includes: a light absorber; a curable resin; and an alkoxysilane. The alkoxysilane includes a dialkoxysilane. Since the alkoxysilane of the light-absorbing composition includes the dialkoxysilane, desired flexibility is likely to be imparted to a light-absorbing layer owing to an organic functional group of the dialkoxysilane while a strong skeleton having a siloxane bond is formed in the light-absorbing layer.
