563-47-3 Usage
Description
3-Chloro-2-methylpropene is used as an intermediate to produce carbofuran, herbicides, plastics, pharmaceuticals and other organics. It is also used as an additive in textile and perfumes. It was used to study ring opening polymerization of oxirane derivatives using organotin phosphate condensate and cationic polymerization of 3-Chloro-2-methylpropene with AICI3 and AIBr3 as initiators. It is also the reactant for the synthesis of cyclobutanone.
Chemical Properties
clear liquid
Uses
Different sources of media describe the Uses of 563-47-3 differently. You can refer to the following data:
1. 3-Chloro-2-methylpropene has been used as reactant in the synthesis of cyclobutanone. It is used as an intermediate in the production of plastics, pharmaceuticals and other organic chemicals.
2. 3-Chloro-2-methyl-1-propene was used to study ring opening polymerization of oxirane derivatives using organotin phosphate condensate. It was used to study cationic polymerization of 3-Chloro-2-methyl-1-propene using using AICI3 and A3IBr, as initiators.
Biological Functions
MAC is a valuable index for clinical anesthesia, but it is
seldom employed without taking other factors into consideration.
For example, inhibiting movement in only
50% of patients is not acceptable. Consequently, if an
inhalational agent were being used alone—that is, without
the administration of other anesthetics or analgesic
drugs—the anesthesiologist would employ a multiple of
its MAC value to ensure immobility.MAC is frequently
multiplied by a factor of 1.3 to achieve nearly 100%
clinical efficacy. On the other hand, useful clinical results
may be achieved with doses of anesthetics below
MAC levels. For example, mild analgesia and amnesia
often occur with doses of inhalational agents that are
near 0.5 MAC. In this state, it may even be possible to
communicate with patients intraoperatively, while their
recall is limited.

Check Digit Verification of cas no
The CAS Registry Mumber 563-47-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 563-47:
(5*5)+(4*6)+(3*3)+(2*4)+(1*7)=73
73 % 10 = 3
So 563-47-3 is a valid CAS Registry Number.

METHOD FOR PREPARING 2-METHYLALLYL CHLORIDE FROM 1,2-DICHLOROTERT-BUTANE
-
Paragraph 0026, (2021/11/26)
The present invention relates to a method for preparing 2-methylallyl chloride from 1,2-dichloro-tert-butane. The method is characterized in that 1,2-dichloro-tert-butane and a sodium hydroxide aqueous solution are used as raw materials; reactive rectification is performed in a combined rectifying tower to eliminate hydrogen chloride so as to obtain 2-methylallyl chloride. A plate type tower is provided at the lower part of the combined rectifying tower; a packing tower is provided at the upper part of the combined rectifying tower; an inner reflux condenser is provided at the top of the combined rectifying tower. The sodium hydroxide aqueous solution is added from a first plate of the plate type tower; and 1,2-dichloro-tert-butane is added from the middle part of the plate type tower. The method has the advantages that the raw material 1 and 1,2-dichloro-tert-butane is fully converted; the selectivity of the 2-methylallyl chloride is high.
Chlorinating preparation method for low-carbon olefins
-
Paragraph 0037-0039, (2020/01/12)
The invention discloses a chlorinating preparation method for low-carbon olefins. According to the method, chlorine gas is diluted with inert gas and then reacts with low-carbon olefins, thus, influence caused by microscopic mixing can be obviously reduced, namely, a too high local temperature can be avoided, thus, side reactions including a decarbonization phenomenon caused by the too high localtemperature can be obviously reduced, and a relatively good chloride yield can be obtained.
