What do these abbreviations refer to?
Thread Content
Abbreviations: Normal boiling point (°C), Density (kg/m3). CCCP: 117, 775.7, 113C: 105, 752.0, 1C3E: 121, 770.6, 1C3H: 120, 788.5. What are the abbreviations for these substances? (The molecular weight is 112.22 for both). Thank you.
The abbreviations were probably created by the designers themselves; you need to describe the process in detail to determine what they mean.
First, what is it used for? What devices are there? What is the raw material?
Based on the approximate ranges of molecular weight and boiling point of these four substances, it is inferred to be an organic liquid. Searching for molecular weight on Baidu may yield: trimethylpentene. Styrene, etc. The repeated appearance of 1 and 3 in the original data name may indicate different substitution positions of three methyl groups and the double bond on pentene. Check the density of trimethylpentene: 770. Conclusion: CCCP: 113; C1C3E: 1; C3H: (omitted)
It’s best to know the purpose; otherwise it’s just pointless effort. If it is seen on a design drawing, there will generally be a legend to explain it.
This is the substance (C8H16) present in the feed composition of the aromatic isomerization unit. Following everyone’s suggestions, I went back to look up information and found substances with similar normal boiling points and densities to use as substitutes, but I don’t know their full names; I hope experts can help correct this.

I completely don’t understand it, but I really want to know. If the original poster finds an answer, please let me know.
It’s a name defined by oneself; no pattern can be discerned
