If not breathing, give artificial respiration. Consult a physician. In case of skin contact Wash off with soap and plenty of water. Consult a physician. In case of eye contact Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician. If swallowed Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

  • Fire-fighting measures: Suitable extinguishing media Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Wear self-contained breathing apparatus for firefighting if necessary.

  • Accidental release measures: Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8. Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Pick up and arrange disposal. Sweep up and shovel. Keep in suitable, closed containers for disposal.

  • Handling and storage: Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2. Store in cool place. Keep container tightly closed in a dry and well-ventilated place.

  • Exposure controls/personal protection:Occupational Exposure limit valuesBiological limit values Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday. Eye/face protection Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Skin protection Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves.

Tetracyano-p-xylene

Arena, Antonella,Bruno, Giuseppe,Panzalorto, Manuela,Patane, Salvatore,Saitta, Gaetano,Scopelliti, Rosario

, p. 2003 - 2005 (1998)

The title compound, C12H6N4, may be considered as the hydrogenated form of tetracyanoquinodimethane. The main property shown in the solid state is luminescence (blue-green emission) and it is due to the stacking interactio

Novel Reactions of TCNQ: Formation of Zwitterions for Nonlinear Optics by Reaction with Enamines

Szablewski, Marek

, p. 954 - 956 (1994)

Zwitterionic adducts of 7,7,8,8-tetracyanoquinodimethane (TCNQ) have been synthesized by the action of enamines on TCNQ.

Bioorganic mechanisms of the formation of free radicals catalyzed by glucose oxidase

Trivi,Leskovac,Zeremski,Vrvi,Winston

, p. 95 - 106 (2007/10/03)

In this communication, we have described the activation of several xenobiotics by glucose oxidase from Aspergillus niger. The following compounds are readily reduced by D-glucose, in the presence of glucose oxidase: p-nitroso-N,N-dimethylaniline, methyl-1
