Mono and bis hexamethylenetetramine iron(III) chloride, Fe(N C ,H ) CI (I) and Fe(N C ,H ) Cl (II) were synthesized by the reaction of iron(III) chloride and hexamethylenetetramine (HMTA) in chloroform. Chemical analysis and spectral results show the coordination of HMTA to the iron(III). Electronic transition spectra of compound I and I1 were also studied in coordinating and noncoordinatin...

Bromine has a strong resource dependence. With the sharp decline of total amount and grade traditional brine resources, difficulty mining is increasing day by day, shortage bromine supply demand become normal situation. Therefore, it urgent to find new sources resources develop corresponding extraction technologies. Bromine-containing waste salt source bromine. The mature technology achievement...

 The major route of exposure is by inhalation.  Acute inhalation exposure to bromine vapour may cause upper respiratory effects, cough, headache, CNS effects and lacrimation.  Acute oral exposure to bromine results in central nervous system effects.  Deep partial skin loss and skin discolouration have been reported following acute dermal exposure to bromine.  Ocular exposure to bromine cau...

OBJECTIVE Inhaled 1-bromopropane decomposes easily and releases bromine ion. However, the kinetics and transfer of bromine ion into the next generation have not been clarified. In this work, the kinetics of bromine ion transfer to the next generation was investigated by using cross-fostering analysis and a one-compartment model. METHODS Pregnant Wistar rats were exposed to 700 ppm of 1-bromop...

Statistical models are developed for bromine incorporation in the trihalomethane (THM), trihaloacetic acids (THAA), dihaloacetic acid (DHAA), and dihaloacetonitrile (DHAN) subclasses of disinfection byproducts (DBPs) using distribution system samples from plants applying only free chlorine as a primary or residual disinfectant in the Information Collection Rule (ICR) database. The objective of ...

We report the first UV-vis spectroscopic study of bromine molecules confined in clathrate hydrate cages. Bromine in its natural hydrate occupies 51262 and 51263 lattice cavities. Bromine also can be encapsulated into the larger 51264 cages of a type II hydrate formed mainly from tetrahydrofuran or dichloromethane and water. The visible spectra of the enclathrated halogen molecule retain the spe...

AIMS To examine the possible consequences of high plasma concentrations of bromine on thyroid hormone. METHODS Bromine was measured by inductively coupled plasma mass spectrometry in the plasma of 799 patients consulting for thyroid disorders. Because the mean (SD) bromine concentration in the plasma of healthy subjects is 4 (1) mg/l, concentrations above 6 mg/l were regarded as outside the n...

ZONDEK AND BIER [1932; 1933] have pointed out that in certain cases of mental disorder (particularly of the manic-depressive type) the blood-bromine is usually considerably lower than normal. Unfortunately they used a method of bromine estimation which is subject to severe criticism and hence, although their conclusions may be correct, the work requires repetition with a sound method of bromine...
