JINTHERM 701 is mainly composed of Monobenzyltoluene (CAS: 27776-1-8), with a chemical formula of C₁₄H₁₄. As a high-quality thermal medium carrier, it can not only operate stably at high temperatures of 340 ℃ for a long time (under pressure), but also act as a refrigerant in low-temperature environments. It has excellent low-temperature fluidity and high-temperature thermal stability, making it very suitable for applications that require flexible switching between heat transfer and cooling functions.

Product Data

Phys Data of JINTHERM 701

Note: The above data are only the typical data of the product. The product is subject to the final analysis.

Material Compatibility

JINTHERM 701 does not corrode the usual metallic materials used in construction of plants and machinery. JINTHERM 701 is compatible with pure graphite, PTFE and fluorinated elastomers. These materials can be used as base materials for seals. In selecting the seals, note must be taken of the seal manufacturer's data for temperature resistance and mechanical strength.

Rubber-elastic binders swell on contact with JINTHERM 701 and should not be used in the seals for JINTHERM 701 plants.

Seals made of pure graphite have proven particularly useful in heat-transfer plants using JINTHERM 701. To increase the strength and dimensional stability, these seals are advantageously provided with a metallic insert, e.g. a sheet metal core.

Toxicological properties and safety

JINTHERM 701 is intended for use as heat-transfer medium in a closed plant. For safety and environmental reasons, escape of the heat-transfer medium is to be prevented or limited to a minimum amount by means of appropriate construction measures. When handling JINTHERM 701, the usual guidelines and recommendations for handling organic liquids should be observed and precautions should be taken.

Storage and transport

JINTHERM 701 has a virtually unlimited storage life when stored in closed metal containers (e.g. aluminium or steel). No special protective measures are necessary during storage of the heat- transfer fluid. When handling JINTHERM 701 and when filling and operating a heat-transfer-system with JINTHERM 701, care must be taken that the heat-transfer fluid cannot enter the soil or sewer system. The product is almost insoluble in water. If necessary, used JINTHERM 701 can be recycled or used for energy recovery observing local regulations.

Experience has shown that JINTHERM 701 charges do not have to be replaced even after many years of use. The limits for reliable use of the heat-transfer fluid will only be reached after long-term use of JINTHERM 701 above its boiling point. In this case, the used JINTHERM 701 can be reclaimed by fractional distillation for reuse as a heat-transfer fluid. However, for economic reasons, amounts of approximately 10 t or more are required for distillation. The values of the residue content of JINTHERM 701, the viscosity and the chlorine content of the goods; the values are to be determined beforehand.
