The present disclosure provides an antibacterial hydrophilic compound. The antibacterial hydrophilic compound may react, induced by light through a hydrogen abstraction group in the structural formula thereof, with a C—H group and thus bind to a surface of a material having the C—H group (for example, chemical fibers such as polyester, chinlon, and the like; plastics, rubbers, and other similar materials), which can impart a durable antibacterial activity and hydrophilicity to the material. The antibacterial hydrophilic compound has a relatively strong binding force to the surface of the material without damaging the mechanical properties of the raw material. The present disclosure also provides a modified material that is modified by the antibacterial hydrophilic compound.

An integrated, co-product capable process is provided for producing taurine in particular with optionally one or both of monoethanolamine and diethanolamine from one or more sugars, comprising pyrolyzing one or more sugars to produce a crude pyrolysis product mixture including glycolaldehyde and formaldehyde; optionally removing formaldehyde from the crude pyrolysis product mixture, then combining the crude pyrolysis product mixture with an aminating agent in the presence of hydrogen and further in the presence of a catalyst to produce at least monoethanolamine from the crude pyrolysis product mixture; optionally recovering diethanolamine from the crude reductive amination product, sulfating at least a portion to all of the monoethanolamine product to produce 2-aminoethyl hydrogen sulfate ester; and sulfonating the 2-aminoethyl hydrogen sulfate ester to produce taurine.
