What is EDC chemical used for?

Ethylene dichloride (EDC) is used primarily for the production of vinyl chloride monomer (VCM), which is used mainly in the polymerization manufacture of polyvinyl chloride (PVC). PVC is commonly used in pipes, fittings, profiles, tubes, windows, doors, sidings, wire, cable, film, sheet, and flooring.

How do you make a chemical DC?

DC Endorsement Procedure

1. Log into the e-governance page on DGShipping Website.
2. Log in to the seafarer profile by entering details on a top-left section of the e-governance page.
3. Click on the “COC, DC Endorsement, GMDSS Radio Operator” section as shown in the below picture.

How do you dry DCE?

Dichloromethane (DCM) and dichloroethane (DCE) were dried by refluxing over CaH2 under N2(g). N-methylpyrrolidinone (NMP) and ethanol were used as commercially supplied (anhydrous/reagent grade). Petroleum spirit (PS, 40-60°C fraction), n-hexane and water (H2O) were purified by distillation.

What is DCM solvent?

Dichloromethane, commonly called methylene chloride, is a solvent that is widely used in chemical research and manufacturing. It is a highly volatile liquid (see fast facts table), but it is neither flammable nor explosive in air. Dichloromethane is commonly produced by chlorinating methane.

Is DCE and cop same?

Answer 26: Both are same. The Dangerous Cargo Endorsement shall hereafter be called as Dangerous Cargo Endorsement or the Certificate of Proficiency in Tankers as per STCW 2010 amendments. We, in India are now using the terminology of Certificate of Proficiency (COP) in Tankers for Dangerous Cargo Endorsement.

What is DC certificate?

Dangerous cargo endorsement is a certificate of authorization for a seafarer, qualifying him/her for working on any vessel dealing with cargo that are categorized as maritime dangerous goods.

What is EDC liquid?

Ethylene Dichloride (EDC) or 1,2-Dichloroethane is a clear, flammable liquid. The liquid is heavier than water. EDC evaporates readily at ambient temperatures. It has a sweet odor typical of chlorinated hydrocarbons. The vapors are heavier than air and tend to sink to low areas.

How do you dry DCE solvent?

How do you remove moisture from a DMF?

Larger amounts of water can be removed by azeotropic distillation with *benzene (10% v/v, previously dried over CaH2), at atmospheric pressure: water and *benzene distil below 80o. The liquid remaining in the distillation flask is further dried by adding MgSO4 (previously ignited overnight at 300-400o) to give 25g/L.
