|
| Description |
|
A clear polar solvent having high boiling and flash points, a low order of toxicity and a mild ether-like odor. It is stable under most conditions and is not hydroscopic or corrosive. Is particularly well suited for applications requiring a water white product or high purity. Examples would be cosmetics, electronics or where recycling of spent material will occur. |

ARCONATE is a cyclic carbonate that reacts with amines to form carbamates, undergoes hydroxy alkylation and transesterification. It can be used as an isocyanate and unsaturated polyester resin cleanup solvent, viscosity reducer in coatings, CO2 extraction solvent, electrolyte in lithium batteries, polar additive for clay gellants, foundry binder catalyst, and textile dye carrier and cleaner. |

ARCONATE is stable under normal storage conditions. However, in the presence of an acid, base, metal oxide or salt, propylene carbonate may decompose liberating CO2. These materials will also decrease thermal stability. In an aqueous solution, the decomposition products would be propylene glycol and CO2. Either situation could potentially lead to pressure buildup in closed containers, which may result in the container rupturing. It is therefore suggested that all such mixtures be tested for shelf life stability. |

| Toxicological |
Propylene Carbonate has a low degree of acute toxicity. Undiluted, it is slightly irritating to skin and may cause minimal to moderate transient eye irritation. It is approved as an indirect food additive and used in cosmetics at concentrations up to 5%. |
| Evaluation |
|
|
|
|
|
|
|
No adverse effects were seen beyond the site of applications in subchronic dermal toxicity studies in rats or rabbits. Additionally, no signs of toxicity have been seen in repeated inhalation studies with rats, dogs, and guinea pigs, although some evidence of respiratory irritation has been reported. |

| Regulatory |
|
ARCONATE is not subject to the reporting requirements of SARA, Title III Sections 311/312 and 313; is not a hazardous substance under CERCLA; is not on the HAP’s list of the Clean Air Act Amendments; or subject to California Proposition 65. |
| Status |
|
|
|
|
|
|
|
|
ARCONATE is on the U.S. TSCA list and is included in the EEC’s EINECS, Canadian DSL and Australian Chemical Inventories. |

|
| Material |
|
|
Carbon steel or stainless steel transfer lines and pumps may be used. Preferred gasket material is Teflon®, but EPR, neoprene, plyethylend, cork and natural rubber are satisfactory, Buna N, Hypalon® and Viton® are not suitable gasket materials. |
| Compatibility |
| Guidelines |
|
|
|
|
Information from material suppliers and specific conditions of contact should be considered in the selection of suitable materials. |
