Escopo e aplicabilidade

This standard applies to solvent for vegetable oils extraction produced from petroleum straight-run fractions, reformed raffinate, or condensate fractions. It is specifically applicable to products primarily used in the extraction of edible oils. Manufacturers and importers of food-grade extraction solvents must comply with this standard to operate in the Chinese market.

Requisitos técnicos

The standard outlines mandatory technical specifications to ensure the safety and purity of the extraction solvent. Key parameters include strict distillation range limits to guarantee optimal volatility during the extraction process. It also enforces rigorous controls on chemical composition, notably setting maximum thresholds for benzene content and sulfur content to prevent toxic contamination in edible oils. Furthermore, the standard defines acceptable ranges for density and limits for bromine index to ensure chemical stability. Compliance with these chemical and physical limits is mandatory for all batch deliveries.

Métodos de ensaio

To verify compliance, the standard mandates specific evaluation procedures. Distillation characteristics are measured following the methods in GB/T 6536. The critical benzene content is determined via gas chromatography as specified in GB/T 17474. Additionally, sulfur content is assessed using either the coulometric method (SH/T 0253) or ultraviolet fluorescence method (SH/T 0689), while visual inspection is required to confirm the absence of mechanical impurities and moisture.

Perguntas frequentes

What products are regulated under GB 16629-2008?

It applies to solvents for vegetable oils extraction primarily used in the extraction of edible oils, produced from petroleum straight-run fractions, reformed raffinate, or condensate fractions.

What are the key updates from the previous GB 16629-1996 version?

The updated version significantly tightens quality and safety limits. For example, the distillation range was narrowed, the general aromatics limit was replaced with a strict benzene content limit of ≤0.1%, and the maximum sulfur content was drastically reduced to ≤0.0005%.

How does GB 16629-2008 differ from international ISO standards?

The standard references several Chinese national (GB/T) and petrochemical (SH/T) testing standards. For instance, it references GB/T 17474 for benzene determination and SH/T 0253 or SH/T 0689 for sulfur content, which share similarities with international ISO methods.
