Manufacturing Methods of Methyl tribromide:
Prepared from acetone and sodium hypobromite.

By heating acetone or ethanol with bromine and alkali hyroxide and recovery of distillation (similar to acetone process of chloroform).

Analytic Laboratory Methods of Methyl tribromide:
To support studies exploring the relation between exposure to trihalomethanes (THMs) and health effects, we have developed an automated analytical method using headspace solid-phase microextraction coupled with capillary gas chromatography and mass spectrometry.

This method quantitates trace levels of THMs (chloroform, bromodichloromethane, dibromochloromethane, and Methyl tribromide) and methyl tertiary-butyl ether in tap water.
Detection limits of less than 100 ng/L for all analytes and linear ranges of three orders of magnitude are adequate for measuring the THMs in tap water samples tested from across the United States.

Method: NIOSH 1003, Issue 3
Procedure: gas chromatography with flame ionization detection
Analyte: Methyl tribromide
Matrix: air
Detection Limit: 6.0 ug/sample.

Method: ASTM D5790
Procedure: gas chromatography/mass spectrometry
Analyte: Methyl tribromide
Matrix: treated drinking water, wastewater, and ground water
Detection Limit: 0.2 ug/L.

Method: EPA-EAD 601
Procedure: gas chromatography with electrolytic conductivity or microcoulometric detector
Analyte: Methyl tribromide
Matrix: municipal and industrial discharges
Detection Limit: 0.2 ug/L.

Clinical Laboratory Methods of Methyl tribromide:
To support studies exploring the relation between exposure to trihalomethanes (THMs) and adverse health effects, an automated analytical method was developed using capillary gas chromatography (GC) and high-resolution mass spectrometry (MS) with selected ion mass detection and isotope-dilution techniques.
This method quantified trace levels of THMs (including chloroform, bromodichloromethane, dibromochloromethane, and Methyl tribromide) and methyl tert-butyl ether (MTBE) in human blood.

Analyte responses were adequate for measuring background levels after extraction of these volatile organic compounds with either purge-and-trap extraction or headspace solid-phase microextraction (SPME).
The SPME method was chosen because of Methyl tribromide ease of use and higher throughput.

Detection limits for the SPME GC-MS method ranged from 0.3 to 2.4 ng/L, with linear ranges of three orders of magnitude.
This method proved adequate for measuring the THMs and MTBE in most blood samples tested from a diverse U.S. reference population.

Ethanol, added as a stabilizer, is removed by washing with H2O or with saturated CaCl2 solution, and the CHBr3, after drying with CaCl2 or K2CO3, is fractionally distilled.

Prior to distillation, CHBr3 has also been washed with conc H2SO4 until the acid layer is no longer coloured, then dilute NaOH or NaHCO3, and H2O.
A further purification step is fractional crystallisation by partial freezing.
