Dibutyltin dichloride is registered under the REACH Regulation and is manufactured in and / or imported to the European Economic Area, at ≥ 10 tonnes per annum.
Dibutyltin dichloride is used in articles, at industrial sites and in manufacturing.
Dibutyltin dichloride (usually referred to simply as DBTC) is an organotin substance that appears colorless to slightly yellowish-brownish at room temperature.
Dibutyltin dichloride is readily soluble in organic solvents such as benzene, toluene, ether and alcohols but is very difficult to dissolve in water.
Decomposition (hydrolysis) occurs in hot water.
Dibutyltin dichloride is flammable, low volatile and has a pungent odor.
Produced by reacting tetrabutyltin with tin(IV) chloride, Dibutyltin dichloride is a catalyst and stabilizer with a wide range of applications and even acts as a fungicide.
Dibutyltin Dichloride is a chemical compound comprising two bromine atoms and two chlorine atoms.
Dibutyltin dichloride is a colorless and odorless substance, with relatively low toxicity.
Dibutyltin dichloride serves as a catalyst for the production of polymeric materials, as well as lubricants and other industrial products.
Dibutyltin Dichloride has been proposed as an enzyme inhibitor, offering insight into Dibutyltin dichloride is impact on polymer synthesis and organic compound production.
Hydrolysis products of dibutyltin dichlorides:
The hydrolysis of di-s-butyltin dichloride yields similar products to those found for the di-n-butyl compound whereas the hydrolysis behaviour of di-t-butyltin dichloride is markedly different.
Distannoxanes are not found in the latter case but instead di-t-butyltin hydroxide chloride is obtained.
Under strongly basic conditions di-t-butyltin oxide is formed which has unusual structural properties and can easily be converted into a ‘dihydroxide'.
Variants of Dibutyltin dichloride:
In addition to the normal Dibutyltin dichloride, BNT also offers dibutyltin dichloride in various versions:
In DIDP solution (diisodecyl phthalate) as a catalyst for adhesives based on polyurethane and for silicone sealants; or in xylene as a catalyst for the production of silicones.
BNT-CAT 410:
Dibutyltin dichloride from the production of BNT is shipped in polyethylene-lined drums of 30 liters or in barrels of 205 liters.
In the closed original packaging, Dibutyltin dichloride has a minimum shelf life of 6 months without loss of quality.
BNT-CAT 411:
BNT-CAT 411 (dibutyltin dichloride in DIDP solution) is liquid at room temperature and colorless to slightly yellowish.
Crystallizations can occur below 10°C, which is why Dibutyltin dichloride must be heated to 35 to 40°C before use and a sample must be taken to determine the homogeneity.
BNT-CAT 411 is supplied in polyethylene-lined drums and can be stored in the sealed, original containers at storage temperatures above 20°C for at least 6 months without quality deviations.
If the temperature is or has been lower, Dibutyltin dichloride may need to be heated for homogenization.
BNT-CAT 413:
BNT-CAT 413 is a colorless liquid with an aromatic odor.
Dibutyltin dichloride is not or only slightly miscible with water.
BNT-CAT 413 is shipped in steel cans with a polyethylene lining.
If the original packaging remains closed, Dibutyltin dichloride can be stored for at least 6 months without loss of quality (storage temperature > 0°C).
If stored at a temperature below 0°C, crystallization may occur.
To homogenize the product again, Dibutyltin dichloride must be heated at 35 to 40°C for approx. 30 minutes before use.

Uses of Dibutyltin dichloride:
Dibutyltin dichloride is used as organotin intermediate, a general-purpose stabilizers for polyvinyl chloride, an esterification catalyst, and a veterinary vermicide and tapeworm remedy.
Dialkyltin compounds are the best general-purpose stabilizers for polyvinyl chloride, esp if colorlessness and transparency are required.
Dibutyltin as well as monobutyltins are used increasingly as esterification catalysts for the mfr of organic esters used in plasticizers, lubricants, & heat-transfer fluids.

Where exposure of an employee's body to dibutyltin dichloride or liquids containing dibutyltin dichloride may occur, facilities for quick drenching of the body should be provided within the immediate work area for emergency use.
Skin that becomes contaminated with dibutyltin dichloride should be immediately flushed with large amounts of water to remove any contaminant.
Workers subject to skin contact with solid dibutyltin dichloride should wash with soap or mild detergent & water any areas of the body that may have contacted any contaminant at the end of each work day.
Eating & smoking should not be permitted in areas where dibutyltin dichloride is handled, processed, or stored.
Employees who handle dibutyltin dichloride should wash their hands thoroughly with soap or mild detergent & water before eating, smoking, or using toilet facilities.
Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing.
Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers.
All contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
Wherever possible, safer substitutes should be used in the place of alkyltin compounds.
When Dibutyltin dichloride is necessary to make and use them handling should be done in enclosed systems equipped with exhaust ventilation.
