Lanthanum chloride is also used in biochemical research to block the activity of divalent cation channels, mainly calcium channels. Doped with cerium, it is used as a scintillator material. [6] In organic synthesis, lanthanum trichloride functions as a mild Lewis acid for converting aldehydes to acetals. [7]
Lanthanide chlorides are a group of chemical compounds that can form between a lanthanide element (from lanthanum to lutetium) and chlorine. The lanthanides in these compounds are usually in the +2 and +3 oxidation states , although compounds with lanthanides in lower oxidation states exist.
The ammonium chloride route refers to a general procedure to produce anhydrous lanthanide chlorides. The method has the advantages of being general for the 14 lanthanides and it produces air-stable intermediates that resist hydrolysis. The use of ammonium chloride as a reagent is convenient because the salt is anhydrous, even when handled in air.
The CuTi 2 structure of the lanthanum, cerium and praseodymium diiodides along with HP-NdI 2 contain 4 4 nets of metal and iodine atoms with short metal-metal bonds (393-386 La-Pr). [10] these compounds should be considered to be two-dimensional metals (two-dimensional in the same way that graphite is). The salt-like dihalides include those of ...
L. Lanthanide trichloride; Lanthanum acetate; Lanthanum acetylacetonate; Lanthanum aluminate; Lanthanum barium copper oxide; Lanthanum carbide; Lanthanum carbonate
Monazite-derived mischmetal typically was about 48% cerium, 25% lanthanum, 17% neodymium, and 5% praseodymium, with the balance being the other lanthanides. When bastnäsite started being processed for rare-earth content in about 1965, it too was converted to a version of rare-earth chloride and on to mischmetal. This version was higher in ...
It's hard to believe one of Sex and the City's most shocking deaths is old enough to order itself a Cosmopolitan.. In a show full of unforgettable moments, season 6's episode 18, aptly titled ...
Firming agents are food additives added in order to precipitate residual pectin, thus strengthening the structure of the food and preventing its collapse during processing. These are salts, typically lactates or phosphates, calcium salts or aluminum sulfates. [1] They are mainly used for (fresh) fruit and vegetables.
