Questions regarding the national standard GB/T 6818-2019 for industrial octanol (2-ethylhexanol)
Thread Content
I would like to ask whether the national standard GB/T 6818-2019 for industrial octanol (2-ethylhexanol) applies only to isooctanol with CAS number 104-76-7 Can isooctanol with CAS 68526-83-0 refer to this national standard? Thank you
The scope of application of GB/T 6818-2019 is explicitly defined as industrial octanol (2-ethylhexanol), namely the product with CAS number 104-76-7. This standard does not explicitly mention or include other isomers or mixtures. The product with CAS number 68526-83-0 usually refers to a mixture of isomers of C8 alcohols, rather than pure 2-ethylhexanol (CAS: 104-76-7). Therefore, strictly speaking, GB/T 6818-2019 is not directly applicable to the isooctanol products of CAS 68526-83-0. However, for practical operational convenience, if the performance parameters of CAS 68526-83-0 are similar to the corresponding specifications in GB/T 6818-2019, companies can generally use these national standards as a reference to establish their own internal control criteria; yet they cannot claim to fully comply with the GB/T 6818-2019 standard. Overall: - CAS 104-76-7: GB/T 6818-2019 applies explicitly ； - CAS 68526-83-0: It can be used for reference, but cannot serve as an accurate basis for determination. .
