BTC trichloromethyl
1. BTC: chemical vocabulary
BTC is the abbreviation of (Trichloromethyl) carbonate. It is the abbreviation of a chemical substance, mainly composed of carbon, chlorine and oxygen. The chemical formula is c3cl6o3, which can be used as the substitute proct of highly toxic phosgene and diphosgene in the synthesis
BTC: enterprise abbreviationBTC refers to BTC Yingqun enterprise from Taiwan, China, which is a large-scale high-tech enterprise developing and procing keyboard, mouse and recorder. BTC is famous for procing high-quality computer peripherals. BTC is the OEM keyboard and add-on card proced by famous brand EMPREX, ranking first in Taiwan, especially the third in the world
BTC: the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was formally born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system BTC: engineering materialBTC (buttress thread coupling), full name of partial trapezoidal thread coupling, is an API standard thread connection type, which is commonly used in the connection of petrochemical pipes or tools, such as floating collar, guide shoe and pipe shoe used in cementing operation
5, BTC: e-commerce mode
BTC (business to customer) e-commerce is one of the categories of e-commerce by trading partners, that is, e-commerce of commercial institutions to consumers. This form of e-commerce is generally based on the network retail instry, mainly with the help of the Internet to carry out online sales activities. BTC is also known as B2C, B2C mode is the earliest e-commerce mode in China
bitcoin is generated by a large number of calculations based on a specific algorithm. Its essence is the special solution generated by a bunch of complex algorithms, and the process of digging bitcoin is to continuously seek the special solution of the equations through a huge amount of calculation. The equations are designed to have only 21 million specific solutions, so the upper limit of bitcoin is only 21 million
so if you want to dig bitcoin, you can use the computer to dig it. You can download the special bitcoin computing tool to do the operation to dig bitcoin
of course, the more professional the equipment is, the greater the probability of being able to dig. Therefore, we will carefully select the right mining machine and pool before digging bitcoin. For example, the BTC guild mine in foreign countries is very famous. As for the mining machine, it is a computer used to earn bitcoin, but the computer is equipped with professional mining chips. After all, bitcoin is a hot card. The price of a miner ranges from two or three hundred yuan to 200000 yuan.
the real price start is in October 2010. Before that, you can buy 10W pieces for 1W yuan. But this is because no one bought it, resulting in extremely low prices. If someone wants to buy 10W, the price will be higher than 1W.
it's been a week, and now it's psychological.
2. This proct is extremely stable at room temperature. It should be sealed and stored in a dry, cool and ventilated place. It is forbidden to mix with alkaline compounds
3. When using or contacting this proct, the operator should wear plastic coated gloves and gas mask, and the personnel should be at the air outlet as far as possible
4. In case of eye irritation or skin contact, rinse with clean water, take a rest in case of accidental ingestion or inhalation, and inject 20% and 20 ml of lotropine in case of oxygen inhalation or serious cases
when used, it depends on the specific reaction system. Generally speaking, if the system contains substances (organic amines, active carbon, organic bases) that initiate its decomposition, the reaction can proceed smoothly without any initiator. Otherwise, 1-5% (weight of the proct) of DMF or pyridine and other organic bases are added to the other phase (generally divided into two-phase reaction, one phase is solid phosgene solution, the other phase is substance reacting with phosgene), and the speed of dropping one phase to the other phase is controlled to control the speed of reaction. The solvents of solid phosgene are benzene, chloroform, dichloroalkane, cyclohexane and so on. This solvent should not be the one to initiate the decomposition of phosgene, while the solvent of the other phase should preferably be the one to initiate the decomposition of phosgene.
