Brown Oil

Physical properties

It is a viscous reddish liquid and is insoluble in vater， but soluble in organic solvents such as acetone,dimethylformamide,cyclohexanone， benzene and xylene. It has a specific gravityof 1.38,a boiling point greater than 120℃ and a vapour pressure of about 0.05 torr. The supplier normally dissolves TCMTB in a mixture of organic solvents to form a concentrate. Emulsifiers or surfactants may be added to the concentrate to improve the stability of emulsions formed when the concentrate is diluted withwater. TCMTB is sold commercially as 80% technical material under thetrade name "TCMTB" by Buckman Laboratories，Which is the soleanufacturer of the material.The patented preparationinvolves a reaction of 2-mercaptobenzothiazole and chloromethylthiocyanate,but confidential data obtained from Buckman Laboratories indicates another preparative method may now be used.

History

The commercial use of TCMTB apparently had its origins in with Buckman Laboratories，Inc., of Memphis，Tennessee. In thelate 1940's this company became involved in the search for solutions to the problem of breaks in paper on high speed paperachines due to the formation of microbiological slime.rhecompany first developed the microbiocide BSM-11,a product containing mercuric acetate and trichlorophenol, which seemed tof ind acceptance in the paper making industry. However, in view of the potentiaL for adverse health and environmental impacts from the use of mercury compounds，BuckmanLaboratories developed a 1ine of organosulphur compounds whichalso proved to be effective slime control agents."Alone， or inconjunction with other active ingredients，TCMTB is now found in avariety of Buckman products.

Uses

2-(Thiocyanatomethylthio)benzothiazole is an antimicrobial agent used as a substitute for chlorophenols in industrial applications.

Uses

Wood preservative, marine biocide, fungicide.

Application

2-(Thiocyanatomethylthio)benzothiazole can be used as:

Industrial antimicrobial used instead of chlorophenols;
Used as a wood preservative, marine biocide, and fungicide;
Used as a contact fungicide for barley, cotton. corn, oats, rice, sorghum. sugar beets, safflower, and wheat;
in seed treatments for cereals, corn, cotton, legumes, rice, sorghum, and sugar beets;
as preservative in paints and leather production;
Used as a wood preservative, biocide (pulp & paper mills, sewage systems), product preservative and slimicide (paper, leather, paint, carpet, textiles, wallpaper), and seed treatment pesticide.

Toxicology

There are few published studies on the toxicity of TCMTB or Busan1030. Confidential information received from Buckman Laboratoriesindicates that most of the toxicity studies on TCMTB and Busan 1030 have been carried out by private laboratories and that this data vas submitted to government agencies as part of the pesticideregistration process. "Unfortunately, this data is not available from Agriculture Canada, but has been requested by the company from the B.C. Ministry of Environment and Parks' wasteManagement Branch .
