What does chemical DCC mean? What does dcc mean

There are various definitions of DCC, which are as follows:

1. DCC: dicyclohexylcarbodiimide.

DCC refers to dicyclohexyl carbodiimide, which is a low-temperature biochemical dehydrating agent used for the synthesis of acids, anhydrides, aldehydes, ketones, etc. For amikacin.

and the synthesis of amino acids, it is a good low-temperature biochemical dehydrator.

It is also used in the synthesis of acids, anhydrides, aldehydes, ketones, etc. In Japan, it is used for glutathione.

of dehydrating agents, accounting for 90% of total consumption. When the product is used as a dehydrating condensation agent, it can be formed by a short-term reaction at room temperature, and the product after the reaction is dicyclohexyl urea.

2. DCC: dial-up control center.

Dial Control Center, or DCC for short, refers to the routing technology used to interconnect routers with each other through the public switched network (PSTN and ISDN). On-demand dialing is available.

3. DCC: American high-tech enterprises.

DCC is a well-known high-tech enterprise in the United States, which produces thermocouples.

Welding machines are mainly used in all areas where thermocouple temperature measurement elements need to be welded, while temperature loggers are used in process monitoring, quality control, field testing, environmental monitoring, research and development, and manufacturing.

4. DCC: Delivery Control Center.

DCC=Deliver Center Control, which means delivery control center, is a department within some large enterprises, responsible for the central control of the entire link from accepting customer orders to shipping to customers and receiving payment.

5. DCC: catalytic cracking process.

Deep Catalytic Cracking Process (DCC Process). The process was developed by the Chinese Academy of Petrochemical Sciences, using heavy oil as raw material, using solid acid selective zeolite catalyst to carry out the cracking reaction under milder reaction conditions.

Production of low carbon olefins.

or process technology for isomeric olefins and high-octane gasoline.

The process draws on the fluid catalytic cracking technology, and adopts the fluidization, continuous reaction and regeneration technology of the catalyst, which has been industrialized.

DCC, also known as dicyclohexylcarbodiimide, is a commonly used water loss agent with the chemical formula C13H22N2 and a molecular weight of 206, which is especially important in peptide synthesis. Odorous white crystals with a very low melting point and soluble in methylene chloride.

Tetrahydrofuran, acetonitrile and dimethylformamide.

But it is insoluble in water. Peptide synthesis, often used as a reaction dehydrating agent.

DCC is dicyclohexylcarbodiimide, which is a commonly used water loss agent with the chemical formula C13H22N2 and a molecular weight of 206, which is especially important in the synthesis of peptides.

n,n'- Dicyclohexylcarbodiimide.

DCC is actually the abbreviation of OCUMENT Control Center, which means document control center. The document control center is not only the administrative function management department of the company's documents and documents, but also the institution that preserves the documents and materials. A lot of important documents and materials will be kept there, so as not to be damaged by people with good intentions.

DCAC stands for DC and AC Power Supply.

DCAC is the network surveillance department established by the Federal Bureau of Investigation (FBI) of the United States, and its full name is Domestic Communications Assistance Center, referred to as DCAC. Its role is to invent more complete technical means to intercept and monitor network communications such as the Internet, mobile phone networks and IP**.

DCAC is broadly authorized and covers all means of communication: from intercepting and discreetly decoding Skype network** software calls to building specially crafted wireless listening hardware, from analyzing massive amounts of data from mobile phone carriers, to having social networks submit turnaround data in response to court orders.

The FBI asked Internet companies not to oppose the new law on the establishment of backdoors, that is, the law requires social networks, IPs**, instant messaging, email and other service providers to set up backdoors for ** surveillance. New laws on social networks and IP** were necessary because "there must be specific solutions for exceptions and unspecified matters." ”

A proposal for network monitoring, which decided to allocate $54 million. Back in 2008, Charles Smith, the head of the FBI's Department of Surveillance** and Technical Operations, wrote to other FBI departments** asking for budget funding for DCAC.

DCC is dicyclohexyl carbodiimide, DCC is a strong dehydration reagent, mostly used for amide filial piety, esters and anhydride.

in the synthesis of . At the same time, DCC has been widely used in the reaction of alcohol oxidation to ketones, primary amide to nitrile, -hydroxy ketone to unsaturated ketone.

It is used for the synthesis and dehydration of amikacin and amino acids, and is a good low-temperature biochemical dehydrator, and is also used for the synthesis of acids, anhydrides, aldehydes, ketones, etc. For glutathione.

of dehydrating agents, accounting for 90% of total consumption.

Uses: Mainly used for the condensation of amino acids in the artificial synthesis of polypeptides. As in FMOC-solid-phase synthesis, the carboxyl group of amino acids.

Amide bond is formed with the amino group of another amino acid.

In order for the carboxyl group to be more susceptible to nucleophile attack, the negatively charged oxygen atom needs to be activated into a better departing group, and DCC plays this role. The oxygen atom of the carboxyl group on the amino acid acts as a nucleophile to attack the carbon atom in the middle of the DCC molecule, so that the DCC and the carboxyl group combine to form the Qiaoyun helvein structure, which makes the nucleophilic attack of the amino group easy to carry out.
