Boron chelate complexes of the general formula are described, where X is either —C(R1R2)— or —C(R1R2)—C(═O)—, in which R1, R2 independently of one another denote H, alkyl (with 1 to 5 C atoms), aryl, silyl or a polymer, and one of the alkyl radicals R1 or R2 may be bonded to a further chelatoborate radical, or X denotes 1,2-aryl with up to two substituents S in the positions 3 to 6 in which S1, S2 independently of one another denote alkyl (with 1 to 5 C atoms), fluorine or a polymer, as well as M+ denotes Li+, Na+, K+, Rb+, Cs+ or [(R3R4R5R6)N]+ or H+, where R3, R4, R5, R6 independently of one another denote H or alkyl with preferably 1 to 4 C atoms.
摘要:
Disclosed is a method of separating NaCl from a NaCl contaminated aqueous LiCl solution involving concentration of the solution, cooling of concentrated solution and separation of the crystallized NaCl. The method is characterized in that the concentration and cooling or cooling of the solution are carried out in the presence of a base, preferably in the presence of 0.3-5 wt % (related to LiCl) of at least one alkaline or alkaline earth hydroxide or at least one easily soluble and difficultly volatile amine.
摘要:
An improved electrophotographic recording material of the type comprising an electrically conductive substrate having a blocking layer composed of an amorphous material including silicon atoms, hydrogen atoms and carbon atoms disposed on the substrate, and a photoconductive layer of hydrogenated amorphous silicon disposed on the blocking layer. The photoconductive layer includes carbon atoms, the blocking layer and the photoconductive layer are doped with an element of Group III of the Periodic Table of Elements, and the ratio of the carbon percentage to the percentage of the element of Group III of the Periodic Table of Elements is the same in the blocking layer and in the photoconductive layer.
