Gu, Feng published the artcileFundamental study on the recovery of gadolinium gallium garnet from slicing dust [generated in wafer manufacture] by flotation, Quality Control of 2016-56-0, the publication is Shigen to Sozai (1991), 107(5), 289-93, database is CAplus.

The separation of Gd Ga garnet (GGG) from green carborundum (GC) by flotation was investigated. GGG was selectively floated from GC by using dodecylammonium acetate as a collector, H₂SO₄ or H₃PO₄ as an activator for GGG, and starch as a depressor for GC. The activation of GGG with H₂SO₄ is caused by the specific adsorption of sulfate ion and by the chem. interaction between sulfate ion and dodecylammonium ion on the GGG surface.

Mamiya, Mitsuo published the artcileFundamental study on the flotation separation of iron hydroxide and gypsum precipitated in the neutralization process. II, HPLC of Formula: 2016-56-0, the publication is Nippon Kogyo Kaishi (1982), 98(1132), 501-5, database is CAplus.

Flotation was applied for the separation of Fe(OH)₃ and gypsum formed in neutralizing the acid drain from an Fe sulfide mine by CaCO₃ or Ca(OH)₂. The flotation of precipitate obtained from the water containing 1 g Fe³⁺/L and 6 g SO₄^2-/L was by dodecylammonium?acetate??[2016-56-0]. The selectivity was affected by the rate of neutralization. Satisfactory results were obtained only when the aging process was introduced in the neutralization at pH 2.9. Starch acted as a selective flocculant as well as a depressor for Fe(OH)₃, and gave satisfactory selectivity even when a rapid neutralization was adopted. These flotation products are upgraded by washing with small volume of water or an acidified saturated solution of gypsum.

The surface activity of higher aliphatic amines and their influence on the phys.-chem. properties of potassium chloride granules have been investigated. Due to their high activity the amines work as hydrophobization and anticaking agents for potassium chloride granules. However, in the presence of moisture amines decrease the mech. strength of the granules.

A new synthetic one-step approach to perform the axial ligand exchange reaction in subphthalocyanines that employs trimethylsilyl-protected nucleophiles as starting materials is reported. Theor. calculations indicate that the exchange reaction proceeds through a similar 4-centered ¦Ò-bond metathesis transition state as the substitution with phenols. This direct method allowed us to synthesize new axial derivatives of singular importance within the chem. of subphthalocyanines, for which the reactivity and x-ray crystalline structure were studied.

A series of boron-containing phenoxyacetanilide derivatives I [R¹ = BPin, B(OH)₂; R² = Me, Et, Ph, Cy, 1-adamantyl, t-Bu, o-carboranyl] were synthesized as hypoxia-inducible factor (HIF)-1¦Á inhibitors. Among the compounds synthesized, carboranylphenoxyacetanilide I [R¹ = B(OH)₂; R² = o-carboranyl (II)] was found to be a potent inhibitor against HIF-1¦Á accumulation under hypoxic conditions and inhibited the hypoxia-induced HIF-1 transcriptional activity in HeLa cells (IC₅₀ = 0.74 ¦ÌM). Compound II (GN26361) suppressed hypoxia-induced HIF-1¦Á accumulation and vascular endothelial growth factor mRNA expression in a concentration-dependent manner without affecting the expression of HIF-1¦Á mRNA.
