C11H20O2 --- 184.3 --- CAS 112-38-9

Undec-10-enoic acid.
Content: 97.0 per cent to 102.0 per cent.

Appearance: White or very pale yellow, crystalline mass or colourless or pale-yellow liquid.
Solubility: Practically insoluble in water, freely soluble in ethanol (96 per cent) and in fatty and essential oils.

A. Refractive index: 1.447 to 1.450, determined at 25 ± 0.5C.
B. Freezing point: 21C to 24C.
C. To 2.0 g add 2 mL of freshly distilled aniline and boil under a reflux condenser for 10 min. Allow to cool and add 30 mL of ether. Shake with 3 quantities, each of 20 mL, of dilute hydrochloric acid and then with 20 mL of water. Evaporate the organic layer to dryness on a water-bath. After re-crystallising twice from ethanol (70 per cent V/V) and drying in vacuo for 3 h, the residue melts at 66C to 68C.
D. Dissolve 0.1 g in a mixture of 2 mL of dilute sulfuric acid and 5 mL of glacial acetic acid. Add dropwise 0.25 mL of potassium permanganate solution. The colour of the potassium permanganate is discharged.

Peroxide value: Maximum 10.
Fixed and mineral oils: To 1.0 g add 5 mL of sodium carbonate solution and 25 mL of water and boil for 3 min. The hot solution is not more opalescent than reference suspension.
Water-soluble acids: To 1.0 g add 20 mL of water heated to 35-45C and shake for 2 min. Cool and filter the aqueous layer through a moistened filter. To 10 mL of the filtrate add 0.1 mL of phenolphthalein solution. Not more than 0.1 mL of 0.1 M sodium hydroxide is required to change the colour of the indicator.
Degree of unsaturation: Dissolve 85.0 mg in a mixture of 5 mL of dilute hydrochloric acid and 30 mL of glacial acetic acid. Using 0.05 mL of indigo carmine solution as indicator, added towards the end of the titration, titrate with0.0167 M bromide-bromate until the colour changes from blue to yellow. 8.9 mL to 9.4 mL of0.0167 M bromide-bromate is required. Carry out a blank titration.
Sulphated ash: Maximum 0.1 per cent, determined on 0.50 g.

ASSAY: Dissolve 0.750 g in 10 mL of ethanol (96 per cent). Titrate with 0.5 M sodium hydroxide using 0.1 mL ofphenolphthalein solution as indicator, until a pink colour is obtained.
mL of 0.5 M sodium hydroxide is equivalent to 92.14 mg of C11H20O2.

In a non-metallic container, protected from light.

Fire Extinguishing Media: Water spray, dry chemical, alcohol foam, or carbon dioxide.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.

6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental  precautions: Do not let the product enter drains, soil or water sources.
Methods and materials used for containment Cleanup procedures and Storage:
Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container.
Large Spill: Corrosive solid. Contain spilled material. Stop leak if without risk. Do not get water inside container. Do not touch spilled material. Use water spray to reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all ignition sources.

7. Handling and Storage

Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. Wash thoroughly after handling. Do not drink, eat or smoke while handling. Avoid contact with skin, eyes and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.

Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like bases, oxidizing agents, reducing agent. Containers may be hazardous when empty since they retain product residues.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits: This product does not contain any hazardous materials with occupational exposure limits established by the region-specific regulatory bodies.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerin, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
