Tetramethylene diethylenetetramine - Basis for disinfectants

ChemBioTech Co. Ltd. has mastered production of a new substance for disinfecting compositions - tetramethylenediethylenetetramine (1,3,6,8-tetraazatricyclo [,8] dodecane, CAS 51-46-7) (TMDETA) available as 50% solution and in dry form (of technical grade and of high purity).

TMDETA has long been known as a disinfectant: since the mid 70's in USA, since the mid 90's of the last century in Russia.

TMDETA is a white crystalline substance with mp = 196-198 °C, which is well soluble in water (up to 50%), also in alcohols.

TMDETA 50% solution is a liquid of light yellow to light orange color with a density of 1,105-1,11 g/cm³, having weak characteristic odor (pH>10). It can be mixed with water to any proportion, it can also be mixed with many surface-active compounds, including quaternary ammonium compounds (in such case efficiency gains are possible due to synergies). It can be used for the manufacture of mixed disinfectant solutions.

Such substance does not irritate, does not form free oxygen or chlorine, it is not aggressive towards wooden, painted and synthetic materials, metals. In addition, it was found to have an anticorrosive effect on metals (including carbon steel and alloys).

In contrast to conventionally known disinfectants based on peroxides, aldehydes, compounds with active chlorine, TMDETA provides a lasting disinfectant effect (with microfilm being formed on the surface) and does not cause addiction of pathogenic microbes. Due to low toxicity (3 hazard grade and 4 grade for working solutions) it can be used in presence of people, animals, birds. Treated surfaces do not require to be rinsed with water.

It can be used to remove various smells (rotting, mold).
Several disinfectants developed in Russia are TMDETA based: "Teotropin", "Dezkonten", "RusDez Universal", "Ekobakterin" etc.

Matt film PM-2

ChemBioTech Co. Ltd. produces Matt film PM-2.
Matt film PM-2 is a substitute brand for such films as «Diamat» and PNCH-KT-1 and is used in high-precision drawing and graphics.

Matt film PM-2 compares favourably with its analogues in that it has a higher transparency (D min < 0,1) and absence of abrasiveness, which improves durability of the drawing tools. Drawing can be performed with the open tools ("Penguin" ink is recommended) and with the technical pens (like Rapidograph).

Matt film PM-2 has a thermally treated base due to which it keeps flatness and does not curl during the drawing process, it has a high stability of linear dimensions (2 mm per 1 sq. m.).

Matt film PM-2 is produced by polymer layer application to one or both sides of a 100 microns thick polyester base. The polymer layer enables affinity with various inks.

This film can be used for copying on a laser printer.

Matt film PM-2 is produced in rolls with weight between 1 kg to 50 kg. It can also be supplied as sheets in custom-adjusted size.

Polyvinilformal foam TPVF-3BF

ChemBioTech Co. Ltd. produces Polyvinilformal foam TPVF-3BF.
Porous Polyvinilformal foam TPVF-3BF is a gas-filled polymer material with three-dimensional cellular structure and high hydrophilicity of the polymer base. It is obtained as a result of acetylation reaction of polyvinyl alcohol (PVA) with formaldehyde in an acidic aqueous medium. It has a high water absorbing capacity (up to 98% of volume and above 700% by weight) due to well-developed porous structure and hydrophilicity of the polymer. It becomes soft and elastic when it is wet and restores its original shape once it is dry.

This foam is used as a filtering and moisture-absorbing material.
In addition to the above mentioned properties, Porous Polyvinilformal foam TPVF-3BF has also high wear and chemical resistance. In view of unique valuable properties, which can be adjusted depending on the application requirements, TPVF can be widely used:
- as reusable pre-filters for air filtration and filtration of organic liquids from water;
- as drains, wicks, feed rollers for water supply, transfer and for use in other water-based systems;
- as plants and microorganisms’ growth medium;
- as water-absorbing filters for purification of refrigerants, diesel fuel and oils.

The material showed good results when it was tested as a filtering material for petroleum products and waste oils by the VNIITECHIM (St. Petersburg) and NPP Qualitet LLC (Moscow). Further trials of the same in diesel fuel filtration and refining by DITO company showed that it was not only purifying the fuel from mechanical impurities but it also helped to remove excess moisture and to significantly reduce fuel contaminants content (such as highly carcinogenic substances - benzopyrenes). Fuel refined in this manner shows characteristics similar to the foreign analogues.

Polyvinilformal foam TPVF-3BF is produced in various formats:
• discs
– diameter 400 ± 50 mm, height from 15 to 100 mm;
– diameter from 270 to 300 mm, height from 50 to 100 mm;
• blocks
– 500 х 500 х 5-7;
– 400 х 400 х 5-7;
• cylinders - height from 300 to 400 mm and diameter 200 mm;
• other formats made-to-order.

Polyvinilformal foam TPVF-3BF is produced according to the standard TU 6-05-2052-87 with changes №1, №2; It’s shelf life warranty period is 10 years from the date of manufacture.
