lecture 10 - next gen explosives

why do we keep developing explosives (3)

• explosives arent clean

  • high nitrogen content reduces creation of CO/C

    • to increase tunability

what can be changed with increasing tunability (4)

• crystal packing

• stability

• detonation products

• tagging

whatv are the 2 groups of explosive materials

energetic and stabilising

what is the order of energic groups

• nitro

• azide

• alkine functioning

• hydrogen peroxide TATP

• mol with high ring strain

• aromatic ring with lots of nitrogen

what is the order of stabilising groups

• benzene, aromatic rings

• amine

what PPE is required (6)

• helmet

• face shield

• leather coat

• kevlar gloves

• kevlar suit

• blast shield

what does an entropically favoured explosion look like

large number of N atoms in small mol

what do azidotetrazoles exhibit

spontaneous explosions

what do nitroiminotetrazoles do

control properties of the azidotetra..

what type if explosive is Azidotetrazoles

primary

what type of explosive is Nitroiminotetrazoles

secondary

what does Nitroiminotetrazoles make when paired with guanidiniums

explosive salts

what analytical tech is best for determining if oxygen balance predicted products are correct

FTIR

why is connectivity important

2 comounds with the same oxygen balance can have different products

why can compounds with the same oxygen balance have different products

due to placement of methyl group

there is a trend between crystal packing and what

impact sensitivity

what other effects does moving the oxygen balance have

chnages impact sensitivity

what can control crystal packing

use of explosive salts

what technique can be used to determine impact sensitivity

XRD
