Abstract

This specification covers cumene (isopropylbenzene) manufactured via a zeolite catalyst process. Cumene shall conform to the following requirements: purity weight percent, alpha-methylstrene, benzene, cumene hydroperoxide, diisopropylbenzenes, ethylbenzene, i-butylbenzene, n-butylbenzene, s- butylbenzene, t- butylbenzene, phenols, n-propylbenzene, sulfur, toluene, total butylbenzenes, total cymenes, total non-aromatics, total GC unknowns, bromine index, appearance, and color.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers cumene (isopropylbenzene) manufactured using a zeolite catalyst process.

1.2 The following applies to all specified limits in this specification: for purposes of determining conformance with this specification, an observed value or a calculated value shall be rounded off to the nearest unit in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29 .

1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

1.4 Consult current OSHA Regulations and Supplier's Material Safety Data Sheets, and local regulations for all materials used in this specification.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
