【化学资料表(中英文):短链氯化石蜡(SCCPs)】短链氯化石蜡（Short-Chain Chlorinated Paraffins, SCCPs）是一类广泛应用于工业领域的有机化合物，因其良好的阻燃性、润滑性和稳定性而被广泛使用。然而，随着对其环境和健康影响的深入研究，SCCPs 逐渐引起了国际社会的关注。
SCCPs 是由石蜡烃经过氯化反应制得的一类碳链长度较短的氯代烷烃，通常碳链长度在 C10 至 C13 之间。根据氯原子的含量不同，SCCPs 可分为高氯型、中氯型和低氯型。其中，高氯型 SCCPs（含氯量约 60%~70%）因具有更强的阻燃性能，常用于塑料、橡胶、涂料及纺织品等产品中。
从化学结构来看，SCCPs 属于卤代烃类化合物，其分子结构中含有多个氯原子，这使得它们在环境中具有较强的持久性和生物累积性。研究表明，SCCPs 在水体、土壤和大气中均能长期存在，并可能通过食物链富集，最终对人类健康构成潜在威胁。
在国际上，SCCPs 已被列入《斯德哥尔摩公约》的受控物质清单，表明其对全球生态环境的潜在风险已被广泛认可。许多国家和地区已开始限制或禁止 SCCPs 的生产和使用，尤其是在儿童玩具、服装和电子设备等消费品中。
尽管如此，由于 SCCPs 在某些工业应用中的不可替代性，目前仍难以完全取代。因此，加强对其生产、使用和废弃处理的监管，以及开发更环保的替代品，成为当前研究的重要方向。
Chemical Data Sheet (Chinese and English): Short-Chain Chlorinated Paraffins (SCCPs)
Short-chain chlorinated paraffins (SCCPs) are a group of organic compounds widely used in industrial applications due to their excellent flame retardancy, lubricity, and stability. However, with increasing research into their environmental and health impacts, SCCPs have gradually drawn the attention of the international community.
SCCPs are a type of chlorinated alkanes derived from paraffin hydrocarbons through a chlorination reaction, typically with carbon chain lengths ranging from C10 to C13. Depending on the chlorine content, SCCPs can be classified into high-chlorine, medium-chlorine, and low-chlorine types. Among them, high-chlorine SCCPs (with chlorine content of approximately 60%–70%) are commonly used in plastics, rubbers, coatings, and textiles due to their stronger flame-retardant properties.
From a chemical structure perspective, SCCPs belong to the class of halogenated hydrocarbons, with multiple chlorine atoms in their molecular structure. This makes them highly persistent and bioaccumulative in the environment. Studies have shown that SCCPs can remain in water, soil, and the atmosphere for extended periods and may accumulate through the food chain, posing potential risks to human health.
Internationally, SCCPs have been listed as controlled substances under the Stockholm Convention, indicating that their potential risks to the global environment have been widely recognized. Many countries and regions have begun to restrict or ban the production and use of SCCPs, especially in consumer products such as children's toys, clothing, and electronic devices.
Despite this, due to their irreplaceability in certain industrial applications, it is currently difficult to completely replace SCCPs. Therefore, strengthening regulation on their production, use, and disposal, as well as developing more environmentally friendly alternatives, has become an important direction for current research.
