CYCLOPENTANE

Cyclopentane, also known as “pentamethylene”, is a kind of cycloalkane with the formula of C5H10. It has a molecular weight of 70.13. It exists as a kind of flammable liquid. It is soluble in alcohol, ether and hydrocarbons and is not soluble in water. Cyclopentane is not a planar ring and has two conformations: envelope conformations and semi-chair conformations. It exhibits red yellow color when having reaction with fuming sulfuric acid while generating nitro cyclopentane and glutaric acid through
reaction with nitric acid

Application scope

Cyclopentane as a new type of foam polyurethane foam, used to replace the destruction of the atmospheric ozone layer of chlorofluorocarbons(CFCS), is now widely used in the production of fluorine-free refrigerator, freezer industry and cold storage,

pipeline insulation and other fields, CFCs and HCFCs will soon be banned ad the ODS deadline is approached by the Montreal Convention, and cyclopentane will become the protagonist of the polyurethane foaming field.

 

Physical and chemical properties and main hazards

This product has a simple asphyxiation and paralysis. People have short-term contact and do not cause symptoms. High concentration requires wearing a self-priming gas mask to avoid ingestion.

 

 

Safety measures and precautions for carriage by ships

The railway transportation time limit of this product is to be shipped by the pressure- resistant liquefied gas enterprise self-provided tanker, and it must be reported to the relevant department for approval before shipment. Mixing with oxidants, halogens, etc. is strictly prohibited. Summer should be transported in the morning and evening toprevent sun exposure. Keep away from fire and heat when you stop. When transporting by road, follow the prescribed route and do not stay in residential areas and densely populated areas.

 

Emergency medical treatment

Quickly leave the scene to fresh air and keep the airway open. If breathing is difficult, give oxygen. If breathing stops, take artificial respiration immediately and seek medical attention.

 

Method for fire fighting

Spray the water to cool the container and, if possible, move the container from the fire to the open space. If the container in the fire has changed color or produces sound from a safety relief device, it must be evacuated immediately. Extinguishing media:

foam, dry powder, carbon dioxide, sand. Fire extinguishing with water is not effective.

It is a moderately active trimerization catalyst used in a wider variety of rigid polyurethane and polyisocyanurate foam and non-foam applications. It is recommended for use as a co-catalyst with other polyurethane and polyiscocyanurate Catalyst.

TEP

Flame Retardant TEP, the chemical name is Triethyl Phosphate, has the best hydrolysis stability among currently available halogenated organic phosphates. Can not dissolve in water, dissolve in most organic solvent, and have good compatibility with resins.Applying as Flame Retardant in the production of acetate fiber, polyvinyl-chloride, PU foams, EVA, phenolics materials. Except the flame retarding, it can also promote the moisture resisting, low temperature resisting, the capability of antistatic and the softness of the materials.

DMCHA(PC8)

DMCHA is a strongly basic, clear, colorless-to-straw liquid tertiary amine. The material has a characteristic amine odor. DMCHA catalyst will darken on standing, with no effect on reactivity. It is readily soluble in most polyols and organic solvents but is essentially insoluble in water

BDMAEE(ZF10，A-1)

BDMAEE catalyst is one of the most active amine blowing catalysts available. Although BDMAEE catalyzes both the blowing and gelling reactions, its unique emphasis on the isocyanate reaction has established it as the industry standard for all types of polyurethane systems where efficient catalysis of the blowing reaction is required.
