🔍 Key Concepts

• Chemical Data Guide for Bulk Shipment by Water tables and how individual chemical entries are structured • Location of Reid Vapor Pressure (RVP) data within each substance’s line of information • How similar amine cargoes are listed and what typical RVP ranges look like

💭 Think About

• First, think about where in the Chemical Data Guide you would look for tert-butylamine and which column or field lists the Reid Vapor Pressure • Consider how the Guide usually presents vapor pressure values (units, temperature conditions, and rounding) and how that might affect your choice among 11, 12, 13, or 14 psig • Ask yourself whether tert-butylamine is characterized as relatively low-, moderate-, or high-vapor-pressure compared with other amines in the Guide

✅ Before You Answer

• Verify you are looking at tert-butylamine and not a similar-sounding amine (e.g., butylamine, isobutylamine) • Confirm the exact psig value shown in the Reid Vapor Pressure field and note that the question wants that specific listed number, not an estimate • Double-check that the units are psig and not another unit or at a different reference temperature that might confuse the value
