Alcohols and Polyols

A nitrated alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

Each notification may be associated with multiple companies.

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

SMALL SPILLS AND LEAKAGE: Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with 60-70% ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with 60-70% ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. STORAGE PRECAUTIONS: You should store this material under ambient temperatures. (NTP, 1992)

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

Drug Information

SYMPTOMS: Structurally similar chemicals may cause methemoglobinemia. (NTP, 1992)

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)

2-(4-Nitrophenyl)ethanol Use and Manufacturing

Methods of Manufacturing

(1) Dissolve p-nitrophenylacetic acid in ether.Heat to 50°C under nitrogen protectionAfter adding lithium aluminum hydride and mixing evenly, Add water, continue stirring for 3h, After the reaction is completed, Reduce the temperature to 0 °C, Add sodium hydroxide solution and water, The concentration of sodium hydroxide solution is 12percent.After standing for 20 minutes, warm to room temperature and add anhydrous MgSO4.After stirring for 30min, The solvent in the filtrate is distilled off, Obtained p-nitrophenyl ethanol;(2) dissolving the obtained p-nitrophenyl ethanol in ethanol, The catalyst was added, nitrogen was introduced, and the temperature was raised to 80°C.Hydrogen gas is introduced under atmospheric pressureStir the reaction for 3h, Filter after cooling, Ethanol is distilled, After the resulting solid is recrystallized, Obtained p-aminophenyl ethanol;The catalyst is a mixture of CeO2, MnO, and ZnO.The mass ratio of lithium aluminum hydride used in step (1) to p-nitrophenylacetic acid is 1:2; the volume of water added dropwiseThe mass ratio to lithium aluminum hydride is 1:1; the mass ratio of sodium hydroxide to lithium aluminum hydride is 3:2 and the second additionThe mass ratio of water to lithium aluminum hydride is 5:2.The catalyst in step (2) is a mixture of CeO2, MnO and ZnO in a mass ratio of 1:2:5;The mass ratio of nitrobenzene ethanol is 3:167.
