3,3'-다이아미노벤지딘 C화학적 특성, 용도, 생산
개요
3,3'-Diaminobenzidine (DAB) is a precursor to polybenzimidazole. DAB is frequently used in the immunohistochemical staining of nucleic acids and proteins. It can also be used to detect fingerprints in blood because that it can be oxidized by hydrogen peroxide in the presence of hemoglobin to give a dark-brown color.화학적 성질
Off-white to brown solid.용도
3,3'-Diaminobenzidine is used as peroxidase substrate and a reagent for spectrophotometric determination of selenium. DAB is used for the immunohistochemical staining of nucleic acids and proteins. As a dark brown dye, was used as an antibody-specific stain to identify the paired antibodies in breast tissue. It may be used for the synthesis of a useful, linear, Schiff-base coordination polymer.정의
ChEBI: 3,3'-diaminobenzidine is a member of the class of biphenyls that is benzidine in which one of the hydrogens ortho to each of the amino groups has been replaced by an amino group. It has a role as a histological dye. It is a member of biphenyls and a substituted aniline.주요 응용
3,3'-Diaminobenzidine is used for preparation of high-strength material such as nucleic acid stain and resistance high-temperature polymers such as bullet-proof vests.?Synthesis
3,3'-Diaminobenzidine can be synthesized by treating 3, 3'-dichlorobenzidine with ammonia in the presence of copper catalyst at high temperature and pressure.주요 응용
3,3',4,4' -Tetraaminodiphenyl (3,3'-Diaminobenzidine) is suitable for the production of fibers based on polybenzimidazole. These fibers are resistant to high temperature and to chemicals. Fabrics made from them do not burn, do not melt in contact with a flame, and do not become hard when carbonized. They are suitable for the production of protective clothing and flue–gas filters and as substitutes for asbestos.제조 방법
15 kg of 98.5% pure 3,3'-dinitro-4,4'-diaminobiphenyl tide product and 45 kg of methanol,0.075 kg of palladium carbon is mixed, and hydrogen gas of 0.85-0.9 MPa is introduced at 55-60 ° C, and stirred for 3 hours.At the end of the reaction, the catalyst was recovered, methanol was recovered, 30 kg of water was added, and the mixture was centrifuged and dried to obtain 9.3 kg of 3,3'-Diaminobenzidine having a purity of 99.3%.The yield was 90.6% (based on 3,3'-dinitro-4,4'-diacetylaminobiphenyl).Safety Profile
Suspected carcinogen withexperimental tumorigenic data. Moderately toxic byingestion. Mutation data reported. When heated todecomposition it emits toxic fumes of NOx.참고 문헌
