Isopropyl biphenyl heat transfer oil is mainly composed of isopropyl biphenyl or its mixture. This type of compound has high thermal stability and excellent heat transfer performance. Its typical characteristics include high purity, low vapor pressure and good thermal stability within a specific temperature range (such as below 330°C). In addition, isopropyl biphenyl heat transfer oil also has excellent anti-coking performance, which can prevent the formation of solid particles and coke scale, thereby ensuring the reliable operation of the heat transfer oil system.

The raw material system for isopropyl biphenyl heat transfer fluid comprises four major categories: biphenyl core materials, isopropylation agents, catalysts and auxiliaries, and solvents/utilities. Regarding biphenyl core materials, industrial biphenyl is primarily obtained through the high-temperature thermal cracking and dehydrogenation of benzene (the tubular furnace method, where benzene vapor passes through red-hot pipes—causing two benzene molecules to each lose a hydrogen atom and bond into biphenyl—with an ideal conversion rate of only 8–12%) or via extraction from coal tar distillation. Chinese manufacturers predominantly employ the condensation-dehydrogenation process involving benzene vapor passing through red-hot furnace tubes; variations in heating methods among manufacturers lead to significant differences in energy and material consumption. This process simultaneously generates approximately 10% terphenyl as a by-product; terphenyl can be further hydrogenated to produce hydrogenated terphenyl (another major class of heat transfer fluid). Regarding isopropylation agents, the synthesis of isopropyl biphenyl utilizes propylene (C₃H₆) or isopropanol (IPA) to introduce the isopropyl group onto the biphenyl ring via a Friedel-Crafts alkylation reaction. As a bulk petrochemical product, propylene's price fluctuations directly impact production costs (ranging from approximately $800 to $1,500 per ton). Regarding catalysts, traditional processes utilized Lewis acid or Brønsted acid catalysts such as AlCl₃ (aluminum chloride) or H₂SO₄ (concentrated sulfuric acid); however, these generated large volumes of acidic wastewater and required acid-resistant equipment. Modern processes have shifted toward solid acid catalysts—such as Y-type molecular sieves and Beta zeolites—enabling cleaner production through catalytic reforming and alkylation. Regarding solvents and utilities, the reaction requires inert solvents (such as alkanes); fractional distillation necessitates substantial steam and electricity, while product purification requires multi-stage distillation columns to separate meta- and para-isomers.

In terms of cost structure, the production cost of isopropyl biphenyl heat transfer fluid is primarily composed of raw materials, energy and utilities, and manufacturing overheads. Raw material costs account for 50–65% of total costs. Within this category, biphenyl (or benzene feedstock) represents approximately 40–50% of raw material costs; isopropylation agents—such as propylene or isopropanol—account for 20–30%; and catalysts and auxiliaries make up 5–10%. Price fluctuations in benzene (approx. $600–1,200/tonne) and propylene (approx. $800–1,500/tonne) are primary cost drivers; significant volatility in benzene prices between 2020 and 2023 compelled producers to adopt multi-source procurement and index-linked pricing contracts to hedge against risk. Energy and utility costs account for approximately 15–25% of the total, covering requirements such as high-temperature heating (approx. 400–500°C) for benzene cracking/dehydrogenation, thermal energy for Friedel-Crafts alkylation, and steam consumption for fractional distillation; energy costs can vary by 20–30% between manufacturers depending on the heating method used (electric vs. gas-fired). Manufacturing overheads (equipment depreciation, labor, maintenance, and environmental treatment) account for approximately 15–20% of costs; environmental treatment expenses vary significantly based on the process—specifically, acidic wastewater treatment (associated with the traditional AlCl₃ process) versus solid catalyst regeneration (associated with the molecular sieve process). While the use of solid acid catalysts, such as Y-type molecular sieves, can drastically reduce wastewater treatment costs, the catalysts themselves are expensive and require periodic regeneration. Packaging, storage, and transportation costs account for 5–10%.
