Quick answer

EDDM (Ethylenedioxydimethanol, CAS 3586-55-8) is a non-triazine based H2S scavenger and biocide supplied at ≥ 90% active substance content. It selectively removes hydrogen sulphide from natural gas, crude oil, produced water, and biogas without raising fluid pH or causing calcium carbonate scaling, making it ideal for offshore platforms and high-scaling environments.

EDDM H2S scavenger

EDDM (Ethylenedioxydimethanol, CAS 3586-55-8) is a non-triazine liquid scavenger used to selectively remove H2S without raising pH or causing carbonate scaling.

non triazine H2S scavenger

A sulfur scavenger chemistry that does not contain nitrogen or amine groups, avoiding spent triazine residues, catalyst poisoning, and salt precipitation.

Vasudev Chemo Pharma manufactures and supplies high-active (≥ 90%) EDDM at our ISO 9001:2015 certified plant in Gujarat, India, for domestic and export markets.

About EDDM — Non-Triazine H2S Scavenger

EDDM (Ethylenedioxydimethanol) is a non-triazine based H₂S scavenger and slow-release formaldehyde donor used for hydrogen sulphide removal in oil and gas production, water treatment, and industrial applications. Unlike triazine-based scavengers, EDDM does not contain nitrogen or amine groups, making it an ideal alternative where triazine by-products (such as dithiazines or spent triazine polymers) are undesirable. EDDM reacts selectively with H₂S at ambient temperature through an exothermic process, converting hydrogen sulphide into non-hazardous by-products without causing salt precipitation, corrosion, or catalyst poisoning. The product is fully miscible with water, operates effectively across a pH range of 6–11, and is compatible with most oilfield and industrial chemical systems. Manufactured by Vasudev Chemo Pharma at our ISO 9001:2015 certified facility in Gujarat, India, EDDM is supplied at ≥ 90% active substance content with guaranteed total aldehyde content > 45%. It is also used as a liquid in-can preservative (bactericide) for water-based systems including metalworking fluids, polymer dispersions, pigment slurries, and concrete additives.

Frequently Asked Questions

What is EDDM (Ethylene Glycol Bis-Hemiformal) H2S Scavenger?+

EDDM (CAS 3586-55-8) is a non-triazine, formaldehyde-release liquid H2S scavenger and biocide. It is designed to remove hydrogen sulfide in crude oil and natural gas pipelines without causing the calcium carbonate scaling or solid precipitation often experienced with triazine-based H2S scavengers.

When should I choose EDDM instead of MEA Triazine?+

Choose EDDM H2S Scavenger when treating sour gas or oil in high-mineral water systems, offshore platforms, or pipelines prone to calcium carbonate scaling. Conventional triazine H2S scavengers raise system pH, leading to scaling; EDDM has a lower pH impact, avoiding scaling.

What is your export shipping capability for EDDM?+

We manufacture and export EDDM globally in 250 kg drums and 1,000 kg IBC tanks. We offer CIF delivery to major offshore and oilfield hubs, including Houston, Jebel Ali, Dammam, and Basra. Our EDDM meets international quality standards with complete GHS SDS and batch COA verification.

Non-Triazine H2S Scavengers — EDDM (Ethylene Glycol Bis-Hemiformal)

Applications, Supply & Global Distribution
