What is sulfide?

OPEC+ is likely to stick to its plan for a small increase in oil production in May despite a surge in oil prices caused by the Ukraine crisis and calls from consumer countries such as the United States for more supply.

Several oil consumers, including the US, have urged producers to boost output further, for the crude price has hit its highest level since 2008 of more than $139 this month. But major OPEC producers including Saudi Arabia and the United Arab Emirates did not raise their output targets, and other countries like Russia avoided talking about the subject of Ukraine.  

OPEC+ is made up of the Organization of Petroleum Exporting Countries (OPEC) and the oil-producing Allies which is led by Russia. Since August 2021, OPEC+ has been sticking to its plan to increase production by 400,000 b/d per month, which will rise slightly to 432,000 b/d from May 1st.

This increase did not mean OPEC+’s concession to consumer countries demanding more oil, but an outcome of an internal recalculation of reference production levels, raising quotas for Saudi Arabia, Russia, Iraq, the United Arab Emirates, and Kuwait.

The supply and prices of many other products in global market like the sulfide will continue to be influenced by the oil supply shortage.


What is sulfide?

In inorganic chemistry, sulfide refers to a type of compound formed by a metal or non-metal with strong electropositiveness and sulfur. Most metal sulfides can be regarded as salts of hydrosulfuric acid. Since hydrosulfuric acid is a weak dibasic acid, sulfides can be divided into three types: acid salt (HS, hydrosulfide), normal salt (S) and polysulfide (Sn).

The compound of -2 valent sulfur, antimony sulfide can be regarded as the salt of hydrosulfuric acid. Metal and sulfur are directly reacted, or hydrogen sulfide gas is passed into the metal salt solution, or sodium sulfide is added to the salt solution, metal sulfides can be produced.

Alkali metal sulfide and ammonium sulfide are easily soluble in water, and their solution appears alkaline due to hydrolysis. The sulfides of alkaline earth metals, scandium, yttrium and lanthanides are more insoluble. When the outer electron configuration of the cation is 18 electrons and 18+2 electrons, insoluble and colored sulfides are often formed due to strong polarization. Most water-insoluble sulfides can dissolve in acid and release hydrogen sulfide. A few metal sulfides (such as CuS, antimony sulfide) that are extremely insoluble can be dissolved with oxidizing acid. At this time, S is oxidized to sulfur and removed from the solution.

In the precipitation. Insoluble metal sulfides have a dissolution-precipitation equilibrium in the solution. By controlling the acidity of the solution, the concentration of antimony sulfide in the solution can be changed, so that insoluble metal sulfides with different solubility can be precipitated out separately. This is the basis for the separation and identification of metal ions with hydrogen sulfide in qualitative analysis.

Uses of sulfides

The antimony sulfide is a catalyst in organic synthesis. Because sulfur-containing organic compounds (such as thiophene) can poison ordinary hydrogenation catalysts, antimony sulfide can be used to catalyze the hydrogenation reaction of sulfur-containing organic substances. Cadmium sulfide can be used to make photovoltaic cells. Lead sulfide is used to make infrared sensors. Calcium polysulfide, barium polysulfide and ammonium polysulfide are fungicides and insecticides. Carbon disulfide is used as a solvent in industry. In addition, carbon disulfide is also used to make carbon tetrachloride. In organic chemistry, carbon disulfide is used to insert -C(=S)-S- groups. Zinc sulfide and cadmium sulfide are used to make phosphors, and high-purity cadmium sulfide is a good semiconductor. Tetraphosphorus trisulfide is used to make matches and fireworks. Tetraphosphorus decasulfide is used to make pesticides, lubricant additives and flotation agents. Sodium sulfide is widely used in the manufacture of sulfur dyes, organic drugs and pulp production. antimony sulfide and barium sulfide are used to make luminous paint.

The COVID-19 pandemic has affected economies and chemical companies in many countries around the world. Measures such as extending holidays and resuming work were taken to control the development of the epidemic, and the normal operation of some chemical enterprises was also affected to some extent.

We provides high quality sulfide with reasonable price. “In order to feedback to old customers, the company is still in full operations to provide sulfide with competitive price.” said Olina, the sales manager.

Chemical production is highly dependent on transportation, and the epidemic affects the circulation of people and materials first. Predictably, none of this is rosy. In densely populated areas with large mobility, the situation of epidemic prevention and control becomes more severe in the later stage. If you are looking for the sulfide, feel free to contact us.
