Dimethylammonium perchlorate 18-crown-6 monohydrate clathrate
The reaction of dimethyl-amine, 18-crown-6, and perchloric acid in methanol yields the title compound, C(2)H(8)N(+)·ClO(4) (-)·C(12)H(24)O(6)·H(2)O. The dimethyl-ammonium cation and the water mol-ecule inter-act with the 18-crown-6 unit: N-H⋯O hydrogen bonds are formed between the ammonium NH(2) (+) group and four O atoms of the crown ether, while the water mol-ecule on the other side of 18-cro...
متن کاملBiodegradation of Hexamethylenetetramine in Anaerobic Baffled Reactor
Due to its structure, hexamethylenetetramine (HMT) is a slowly biodegradable substance, hydrolysing in acid environment to ammonium and formaldehyde. Formaldehyde is toxic under normal conditions for biological treatment processes. Following an adaptation, a formaldehyde concentration of 1000 mg·l may become biodegradable both in aerobic and anaerobic conditions. Acidic conditions for hydrolysi...
متن کاملClathrate hydrates in nature.
Scientific knowledge of natural clathrate hydrates has grown enormously over the past decade, with spectacular new findings of large exposures of complex hydrates on the sea floor, the development of new tools for examining the solid phase in situ, significant progress in modeling natural hydrate systems, and the discovery of exotic hydrates associated with sea floor venting of liquid CO2. Majo...
متن کاملPolymorphism in Br2 clathrate hydrates.
The structure and composition of bromine clathrate hydrate has been controversial for more than 170 years due to the large variation of its observed stoichiometries. Several different crystal structures were proposed before 1997 when Udachin et al. (Udachin, K. A.; Enright, G. D.; Ratcliffe, C. I.; Ripmeester, J. A. J. Am. Chem. Soc. 1997, 119, 11481) concluded that Br2 forms only the tetragona...
متن کاملA Clathrate Uncertainty Principle
The crystal engineering design of new clathrate hosts that employ intermolecular attractive forces much weaker than hydrogen bonding and coordination complexation remains problematic. One approach has been to prepare a series of V-shaped molecules with C2symmetry, a small degree of conformational freedom, and protruding halogen atoms. This design has been highly successful (95%), but little pre...
