树脂溶剂的生产工艺流程
英文回答：
Production Process of Resin Solvent.
The production process of resin solvent involves several key steps:
1. Feedstock Preparation.
The starting materials for resin solvent production include hydrocarbons, such as naphtha or kerosene, and olefins, such as ethylene or propylene.
These feedstocks are pretreated to remove impurities and adjust their composition to meet the desired specifications.
2. Thermal Cracking.
The feedstocks are subjected to high temperatures (500-800°C) in the presence of a catalyst.
This thermal cracking process breaks down the hydrocarbon molecules into smaller fragments, including olefins, aromatics, and paraffins.
3. Dimerization.
The olefins produced in the thermal cracking step are reacted with themselves in a dimerization process.
This process involves the combination of two olefin molecules to form a dimer, which is a more stable and higher-molecular-weight compound.
4. Hydrogenation.
The dimers undergo hydrogenation, where hydrogen gas is added to their double bonds.
This process saturates the dimers, converting them
into more stable and less reactive paraffins.
5. Distillation.
The product mixture from the hydrogenation step is subjected to distillation to separate the desired resin solvent from other components.
The distillation process involves vaporizing the mixture and condensing the desired fractions at different temperatures.
6. Final Product.
The final product is a colorless liquid with a characteristic odor.
It is composed primarily of paraffins, with a molecular weight typically ranging from 150 to 300.

树脂溶剂生产工艺流程。

树脂溶剂的生产过程主要包括以下几个步骤：
1. 原料预处理。

树脂溶剂生产的原料包括烃类（如石脑油或煤油）和烯烃（如乙烯或丙烯）。

对这些原料进行预处理以去除杂质并调整其组成以满足所需的规格。

2. 热裂解。

在催化剂存在下，将原料加热到高温（500-800°C）。

这个热裂解过程将烃类分子分解成较小的片段，包括烯烃、芳烃和石蜡。

3. 二聚反应。

在热裂解步骤中产生的烯烃在二聚反应中与自身反应。

这个过程涉及两个烯烃分子结合形成二聚体，二聚体是一种更稳定、分子量更高的化合物。

4. 氢化。

二聚体经过氢化，在这个过程中，氢气被添加到其双键上。

这个过程使二聚体饱和，将其转化为更稳定、反应性更低的石蜡。

5. 蒸馏。

从氢化步骤中得到的产物混合物经过蒸馏以将所需的树脂溶剂与其他组分分离。

蒸馏过程涉及汽化混合物并在不同温度下冷凝所需的馏分。

6. 最终产品。

最终产品是一种带有特征性气味的无色液体。

它主要由石蜡组成，分子量通常在150到300之间。
