Maleic Anhydride (Formula: $C_4H_2O_3$, CAS No. 108-31-6) is a vital organic intermediate utilized extensively across polymeric synthesis, agricultural manufacturing, and specialized coating industries. Its high reactivity, derived from the presence of both an anhydride group and an olefinic double bond, renders it an indispensable building block for developing advanced materials. This technical whitepaper explores the critical parameters of Maleic Anhydride, focusing on CE certification requirements, manufacturing pathways, and functional applications.
For industrial chemicals entering the European Economic Area (EEA), regulatory compliance is a mandatory precursor to procurement. While CE markings typically apply to downstream products, chemical intermediates like Maleic Anhydride must undergo stringent validation processes. These processes align with REACH compliance (Registration, Evaluation, Authorisation and Restriction of Chemicals) and CLP classification regulations. Achieving recognized certificates (such as those issued by German BV - Bureau Veritas and ISO 9001:2015) provides buyers with verified assurance of product safety, batch consistency, and chemical purity.
International industrial standards define the grade of Maleic Anhydride primarily through its solidification point, purity level, and color index (APHA). High-grade Maleic Anhydride exhibits a minimum purity of 99.5% and a molten color value under 25 APHA. Shandong Pulisi Chemical ensures that all batches meet or exceed these benchmarks, supported by ISO 9001 and third-party validation (SGS), facilitating smooth customs clearance and regulatory alignment in European and global markets.
Globally, two primary chemical pathways dictate the production of Maleic Anhydride. Understanding these routes is essential for strategic procurement managers evaluating cost structures and ecological footprints:
| Parameters | N-Butane Oxidation Route (Modern Standard) | Benzene Oxidation Route (Traditional) |
|---|---|---|
| Primary Raw Material | N-Butane ($C_4H_{10}$) | Benzene ($C_6H_6$) |
| Environmental Impact | Low carbon emissions; benzene-free emission profile. | High VOC emissions; benzene is a regulated carcinogen. |
| Catalytic System | Vanadium-Phosphorus-Oxygen (VPO) catalyst. | Vanadium-Molybdenum catalyst. |
| Economic Efficiency | High yield, optimized raw material cost efficiency. | Higher sensitivity to crude oil and benzene pricing cycles. |
| CE & European Preference | Highly preferred due to lower toxicity in production life cycles. | Subject to high environmental tariffs and strict regulatory limits. |
Maleic Anhydride's versatility makes it a critical feedstock in several high-performance industries:
Selecting the right supplier involves assessing both product quality and supply chain resilience. Purchasing from Shandong Pulisi Chemical provides distinct advantages:
Textile, Printing, Dyeing & Leather Solutions
Agriculture, Food & Feed Additives
